Bitcoin Blackjack Strategy Guide

Crypto gamblers have more reasons to be excited as blockchain casinos are starting to integrate Bitcoin blackjack into their game selection. With crypto casinos gaining more exposure, we’re exploring if the decentralized version of the 21 game is more profitable than its traditional counterpart, what are the best ways to start gambling with crypto, and which casinos offer the best odds. Next, let’s dive into our 2023 guide!


The Difference Between Crypto Blackjack and Regular Blackjack

There’s little difference between the game’s regular and crypto versions of the game. The most obvious one is the fact that the regular version is played off-chain using FIAT currency like USD, EUR, GBP, or other government-regulated currencies. The later version is played using popular cryptocurrencies like Bitcoin, Ethereum, or other major ones.

Moreover, regular crypto is played either in physical casinos or on platforms that only allow credit card or FIAT deposits. The crypto version of the game has some restrictions in the sense that you can only find the game in a select number of casinos, and you can deposit using Bitcoin, meaning you need a crypto wallet to make the transfer. Finally, some crypto Blackjack games are played on-chain, so you might have to connect your wallet directly to the website, and this allows for complete anonymity when gambling. The difference lies in the currency you use for gambling and hitting the magical twenty-one.

What to Know Before Choosing to Play Crypto Blackjack

If you’re attracted to playing your blackjack hands on something that’s decentralized, it’s essential to know some specifics about the Bitcoin version of the game. The most important tip we have for players is that they’re playing on platforms that are only partly regulated, and even though the game plays the same as on casinos like Stake, there is the risk of withdrawals.

The flip side of things is that you have the option to experience anonymous play and not have issues withdrawing. But, of course, that’s only the case if you’re playing on-chain and every pot has a unique transaction ID.

It’s essential to know what kind of cryptocurrencies are allowed on the casino if Bitcoin withdrawals are instant, if the casinos require permissions or if the game variant it’s on you’re familiar with. So let’s explore some important elements you need to know to overcome your opponent in a blackjack game.

House Edge in Crypto Blackjack

When it comes to playing crypto blackjack, understanding the house edge is key. This is the percentage of each bet the casino expects to keep as profit over the long term. This edge is usually around 0.5-1% in traditional blackjack, but this can change for crypto blackjack since not all cryptocurrency casinos have the same fees or payout structure. The fact of the matter is that some decentralized blackjack games have a much higher house edge, which can directly affect your ability to count cards.

For example, if you’re playing at a casino with a 5% commission on wins, the house edge jumps up to 5.5%. So it’s important always to be aware of what kind of commission the casino takes before you start playing; otherwise, you could quickly find yourself losing money in the long run.

What’s important to know is that house edge impacts you as a player only when you are playing for a more extended period. Otherwise, you’re just basing your winning on chance.

Crypto Blackjack Myths and Misconceptions

One of the most common myths about crypto blackjack is that it is especially risky. This isn’t true, as crypto blackjack is a much safer and transparent way of playing the game since most transactions and outputs are verifiable on the blockchain. As with all forms of gambling, you should always ensure that the blockchain casino of your choosing has some security features and that your funds are secure.

Another myth about crypto blackjack is that it is complicated to play. This could not be further from the truth; in fact, anyone with a basic understanding of how the 21 game works and knows how to work their way around a crypto casino quickly access and play the game. The only struggle you might face is adding crypto to your wallet accounts since gaming rules are the same.

Finally, there is one myth that some people have perpetuated – that crypto blackjack is a scam. While some platforms are indeed shady, that’s the case for almost every industry, and you should conduct proper research to ensure you’re not getting scammed. If you follow our advice on which casinos are safe and secure and read the full terms and conditions, the blackjack game will seem as seamless as a traditional game.

Available Cryptocurrencies

There are a few different cryptos that you can use to play crypto blackjack. The most popular options are Bitcoin, Ethereum, and Litecoin. All of these have been around for a while and are well-established cryptocurrencies, which most crypto casinos list as available options.

Bitcoin is the original cryptocurrency and is still the most popular option for gambling. Even though it has a much slower transaction speed, every crypto casino has BTC listed as a payment method. What’s more is that other cryptos such as Monero, Ethereum, Litecoin, Dogecoin, or even Bitcoin Cash are available.

Regardless of the token, if casinos are party regulated, each crypto deposit will be converted into platform tokens, and only withdrawals will be made available using crypto. If you play on an on-chain casino and connect directly with your crypto wallet, all transactions will take place on-chain; however, these will be much slower.


The token is getting more widely accepted as it targets younger audiences and has been around for several years.


Following the Ethereum merge and the shift to PoS, Ethereum can process transactions much faster with.


Monero allows players to have complete gaming anonymity; however, only a few casinos accept the token as a payment method. If you want to play using Monero, you can find that on casinos with high anonymity features.


The token was developed as a peer-to-peer token and had a much faster transaction speed than BTC transfers. Litecoin is among the top 3 accepted tokens on crypto gambling casinos as it has good token liquidity.

Bitcoin Blackjack Variations

There are a few different Bitcoin blackjack variations that you can play. The most popular option is the classic (American) blackjack, which is played on most traditional or crypto casinos, European blackjack, Spanish 21, and blackjack switch. These games have been around for some time, some more popular than others; however, crypto casinos do list them, especially the American version of the game.

Bitcoin blackjack

This is the most popular game variant and is similar to the traditional blackjack game you would find in a conventional casino. The same rules apply to the decentralized game version as in casinos. The main difference is that you are using Bitcoin to play, which gives you the added advantage of being able to gamble with cryptocurrency.

Spanish 21

This variant follows the same rules as the classic game, with one exception – the dealer cannot bust on a soft 17. This makes the game slightly more challenging for players and more rewarding in terms of BTC if you win.

European blackjack

The European version of the Bitcoin 21 game is much different than the traditional one. For starters, there are no hidden cards in the game, and the dealer only gets his cards when all players have taken action on their cards.

FREE game

Free games are self-explanatory, and players don’t bet real money when playing. Instead, they join a Bitcoin casino and play any hand they want, but instead of crypto, they only use free tokens. None of the winnings can be withdrawn from the game.

Bitcoin Blackjack Rules

Bitcoin blackjack is a game that follows the same basic rules as standard blackjack, where the game’s objective is to beat the dealer by getting a higher score than him without going over 21.

Most of the time, the minimum bet on Bitcoin games starts at 0.001 BTC, but this can vary depending on the casino you intend to play. If you’re playing on-chain, the system will send the amount to the casino’s address; however, bets are made instantly if you’re playing in regulated casinos.

At the start of each round, you have between 15 to 20 seconds to place your bets before the dealer accepts the bets and starts dealing cards. Once the bets are in, you are dealt two cards face up, and the dealer is dealt one card face up and one face down. Of course, this varies for specific game iterations, but we’re only discussing classic blackjack, popular on Bitcoin live and table games.

Once you get to see your cards, you can either hit (take a card), stand (not take any card), double down (get one card and double your initial bet) or split (this is possible only when you are dealt two of the same number cards). 

If you choose to hit, you are given another card, and you can decide if you want to stand or continue. If you stand, your hand is finished, and the dealer’s second card is revealed. The dealer must then hit if their total is 16 or less and stand if their total is 17 or more. 

The winner is the player with the highest score that doesn’t exceed 21. If you and the dealer have the same number is called a push, and you get your winnings back. However, you lose all your bet if you go over 21 with your cards, and this is a tricky spot to be in, especially when you have cards between 17 and 12. We will dive into that aspect in a later section, discussing strategies.

What are the odds of winning crypto blackjack?

The odds of winning crypto blackjack depend on a number of factors and primarily take into account the platform and the type of games you are accessing. The odds are always in favor of the house, but there is still a good chance of winning if you follow a good strategy and are mindful of your bankroll – more in a later section.

Bitcoin blackjack has a house edge of around 1%, but this can vary depending on the casino platform. Ethereum blackjack, on the other hand, can have a house edge of 2.5%. For every $100 bet, the casino expects to keep $1 or $2.50, respectively. The odds are slightly better for Litecoin blackjack, with a house edge of around 1.5%.

However, these figures can change depending on the casino’s rules. For instance, some casinos allow players to split their cards more than once, while others prohibit doubling down after splitting. So, read the casino’s terms and conditions carefully before playing to understand the exact odds you’re facing.

In fact, with a bit of skill and luck, players can often beat the dealer and walk away with a profit. It just means you are playing against slightly stacked odds, and the key to winning is learning and mastering the basic strategy of blackjack. Then while you are still relying on odds for better turnarounds, you can improve your odds by beating the system.

Get Started With Cryptocurrency Blackjack

Cryptocurrency Blackjack is an online casino game similar to traditional Blackjack, which uses crypto as a payment/deposit method. To get in the habit of accessing crypto blackjack games, players need to cover a few details to get started.

Even if it looks complicated, playing on a crypto platform is not that hard, especially after you figure out precisely what you need to make the process seamless.

If you’re interested in getting started in cryptocurrency blackjack, there are a few things that you need to know:

  1. First, you’ll need to find an online casino that offers the game. There are a number of different casinos that accept cryptocurrencies, including Stake, 1xBit, Rollbit, or BC.GAME. If you need help finding one, you can check out some of the casinos from our vetted list.
  2. Next, you’ll need to set up a cryptocurrency wallet to store your cryptocurrency funds while playing the game. Several different wallets are available, but you should always have both a cold and hot wallet to ensure you keep your winnings safe. Check out the list of verified crypto wallets on our page.
  3. Purchase crypto from an exchange and send the crypto amount to your wallet. Ensure the wallet is compatible with the crypto you want to use; otherwise, you might lose some of your funding.
  4. Finally, you’ll need to buy some cryptocurrency. The most popular cryptocurrencies for blackjack are Bitcoin and Ethereum, but several other options are also available. You need to check out which crypto deposits are available on the casino you choose to play, as there’s no real shortage of choices.

Once you have this setup, you can start playing live or programmed games.

How to Start Playing Blackjack with Crypto?

Step 1: Register to get a cryptocurrency wallet.
Step 2: Buy cryptocurrencies from a centralized/decentralized exchange.
Step 3: Search for a casino that offers the game you want.
Step 4: Sign up using a referral to take advantage of the casino's bonuses.
Step 5: Connect your wallet to the platform.
Step 6: Deposit the amount you wish to wager.
Step 7: Select the game and start playing

Where to Play Blackjack with Crypto?

There are many options for playing blackjack with crypto or offering crypto as a deposit method. There are also a handful of preferred choices for players that want to gamble anonymously and only use crypto without ever signing up to a casino, only by using their wallet as registration.

Players looking to play blackjack with cryptos such as Bitcoin, Ethereum, or other known tokens can do so on well-known and reputable sites such as BitStarz, FortuneJack, mBit Casino, Stake, or RollBit.

It is worth mentioning that you can start playing on Bitcoin or Litecoin Casinos where you can deposit using that payment method. Depending on the platform, it can also offer TRON, Bitcoin Cash, Solana, Matic, or other lesser available deposit methods. What’s granted is that you can at least deposit using major tokens like BTC, ETH, BCH, LTC, and even stablecoins like USDT.

When choosing an online casino to deposit, it’s essential to do your research. Review reviews from other players, read the terms and conditions or check out in-depth reviews about the casino on dappGambl.

How to Play Crypto Blackjack

Crypto blackjack is one of the easiest ways to gamble with cryptocurrency. The game is played just like regular blackjack, but players can enjoy the benefits of blockchain technology, such as provably fair gaming and anonymity.

The first thing you have to do is to select one of the many casinos with crypto availability. Then, send crypto to the wallet address and access the game. Then the fun begins!

Once you’re in the game, the way you play it is the same as its traditional counterpart, the main difference being that you’re playing against a computer rather than another player. If you opt for a live game, you’re playing against another human. Still, your goal is to get as close to 21 without going over it. 

Always remember that you’re playing against the dealer, not the other players. Therefore, you must follow a few tips to not annoy other players on the table and increase the chances of winning:

How to Win at Crypto Blackjack

Blackjack, also known as 21, is played with one or more decks of cards. If you are good at card counting, you can beat the dealer and find the hot shoe. There are a few ways to win at blackjack: playing the number game and automating the game or playing the live version and making sure you’re paying attention to the cards.

You win the game if you beat the dealer, meaning you have cards bigger than the dealer’s but don’t exceed 21. What’s over 21 is a bust. The best way to do so is to avoid hitting cards that are 17 or over. Instead, double down on 11 and 10 cards, giving you a bigger profit margin.

Finally, you can win at crypto blackjack by ensuring you follow the game’s basic strategies and play together with other players.

How to Lose at Crypto Blackjack

A sure way of losing is to not pay attention to anything we’ve mentioned above. For example, hitting on 18, splitting two face cards when the dealer also has a face card, or even making reckless bets above your bankroll.

As a game of chance, the odds are only sometimes in your favor; however, you can minimize the risks by making sure you’re following blackjack logic. Don’t stand on cards below a 10; minimize your bet exposure by not doubling down on a 5. It’s not about how you play but how you minimize your losses.

Blackjack Crypto Strategies

Many different blackjack crypto strategies can be used to win the game. But one method you should consistently implement is to always be in the present, don’t let yourself get easily distracted, and avoid doing any substances that could impair your way of thinking logically.

It would help if you took note of existing rules and actions, especially to be on the same playing level as all the other players, making some strategies easier to act out.

As a general rule, the best strategy you can start implementing is to look for provably fair casinos, find games with a high RTP and play on casinos with low to no deposit fees. While these strategies are not directly related to your playing strategy, they give you an advantage.

Below we explore some of the best and worse blackjack strategies you can implement.

The Best Crypto Blackjack Strategies

Many different strategies can be used to always be on the winning end of every game, and even though some are much more powerful and effective than others, it’s worth considering all of them if you want to get ahead of the competition.

Martingale system

This system is probably the best-known strategy. It’s a simple system that involves doubling your bet after every loss until you win. This system is designed to recover any losses you may have incurred and make a profit. However, the Martingale can be risky, as it can quickly lead to significant losses if you keep losing bets.

Labouchere system

This is another popular strategy to implement; however, it’s a little more complex than the Martingale, but it can be more profitable. With the Labouchere system, you create a sequence of numbers (usually 1-6) and bet an amount equal to the first number in the sequence plus the second number in the sequence. If you lose a bet, you add the amount you lost to the end of the sequence; if you win, you subtract the amount you won from the beginning of the sequence. This system helps to minimize losses and maximize profits.

D'Alembert system

The system offers another option to outperform the dealer, and it’s less risky than the Martingale and has a lower profit potential. With the D’Alembert system, you increase your bet by one unit after every loss and decrease your bet by one unit after every win. This system helps minimize losses and ensures that you only lose a little money if you have bad luck.

The Worst Crypto Blackjack Strategies

You have to make sure that the strategy you follow is, in fact, one that can yield you good results. Unfortunately, while there is a lot of good advice out there, there is similarly as much bad advice regarding your strategy. Below are three examples of methods you should not follow if you play using crypto.

Trying to Count Cards

This is a strategy that definitely does not work when you are playing blackjack with cryptocurrency. The reason is that the deck is constantly shuffled, so it is impossible to keep track of all the cards that have been played. Even more so, you might be getting an automatic shoe, or you’re playing a digital game where the computer sets the odds of winning rather than the deck of cards.

Playing at Multiple Tables

This is another strategy that is unlikely to work when you are playing with crypto. The reason is that it can be challenging to keep track of all the different games going on, and you may be unable to make the best decisions for each of them. You can opt for playing 2-3 sets on the same table, but never play multiple games, especially if they are different.

Betting Too Much

This is a mistake many people make when playing because you can easily get caught in the gambling excitement and lose track of your goal and your bankroll.

Crypto Blackjack Tip And Tricks

  • Look for a game with low house edges. The house edge is the percentage of each bet that the casino takes as profit. The lower the house edge, the better your chances of winning.
  • Make sure the game is fair. Many online casinos offer fair and honest gameplay. Do your research before you choose a casino to play at.
  • Look for bonuses and rewards. Many casinos offer bonuses and rewards to players who bet large amounts of money. If you want to increase your chances of winning, look for casinos with high bonus percentages.

Now that we’ve covered some of the basics, let’s take a look at some specific crypto blackjack strategies that you can use to improve your chances of winning:

Always split pairs of 10s and Aces. This is one of the oldest and most trusted blackjack strategies in the book. Splitting 10s gives you a chance to win twice as much money, and splitting Aces gives you a chance to draw another card and hopefully improve your hand.

Never split 5s or 2s. Splitting 5s or 2s is usually not a good idea because it increases your chances of losing money. The exception to this rule is if you have a hand of 4s and the dealer shows a 6. In this case, you should split the 4s to get the best possible outcome.

Always double down when your hand totals 11. Doubling down means that you double your bet and then draw one more card. This allows you to improve your hand without risking any additional money. However, remember that doubling down with a 9 or 10 can be risky, so use this strategy only when you’re confident about winning.

Don’t take insurance bets. Many casinos offer insurance bets as an option for players who think they might lose their original bet. However, taking insurance usually isn’t recommended because it’s often not worth the risk of losing even more money.

When starting, get into the habit of using a strategy chart. This helps you play blackjack correctly and lets you know when to hit or stand on a set of cards.

Always be aware of the dealer’s cards, as this changes how you play your cards. For example, if a dealer has a K or J and you also have a K or J, you should not double down since there is a big chance that you will bust or at least push.

What are some Common Blackjack Mistakes?

When playing crypto blackjack, it’s important to be aware of the risks involved and to make sure that you don’t make any mistakes that could cost you money. Here are some of the most common mistakes made by blackjack players:

  1. Not understanding the rules of the game. This mistake can cost you money, as you may not know when to hit or stand or when to double down or split your cards.
  2. Playing too aggressively. Again, this can be a costly mistake, as you may end up losing more money than you can afford to lose.
  3. Not using a strategy. If you don’t use a strategy, you’re essentially just gambling, and your chances of winning are slim to none.
  4. Not betting enough money. This can also be a costly mistake, as you may not win as much money as you could if you were betting more.
  5. Betting on the wrong hand. This mistake can cost you money, as you may end up betting on a hand that is likely to lose.

How to Find the Best Crypto Blackjack Games?

Finding the best games and platforms to play on can take time and effort, especially since many casinos offer blackjack games. If you are new to crypto gambling and still want to find a suitable game that meets your needs, has a high level of security, provides a good bonus, and offers fast and secure withdrawals and deposits.

The first step you can do is to check out the dappGambl website and find the best casinos where you can play using Bitcoin, Ethereum, Litecoin, or other specific cryptocurrencies. This will give you a good overview of how trustworthy casinos are, what deposit methods are accepted, and how we rate the casino based on specific metrics.

It’s self-explanatory, but the casino gives games value. The better the casino odds, the higher the chances of winning and having a great experience. Here are some quick tips on how to find the best blackjack games on crypto casinos.

1. Search our website for casino reviews.
2. Ask other players where they play.
3. Join crypto casino forums where they discuss odds
4. Look for casinos that have only a few games, including crypto blackjack.

Top 3 Bitcoin Blackjack Sites Compared


BC.GAME is one of the most trusted crypto gambling platforms on the market. As a crypto-friendly casino, BC.GAME lets players sign up using crypto wallets like Metamask or Walletconnect, and players can sign-up for a juicy welcome bonus of up to $20.000 with four deposit rounds between 180% and 240%. Each bonus is awarded in BCD tokens and is the equivalent of 1 USDT. 

One important aspect is that BC.GAME offers asset security despite being a crypto casino, and players can take full advantage of the casino’s high-end providers like Evolution Game or NetEnt. In short, players looking for a serious casino with a high ranking to play crypto blackjack digitally and with a live dealer should consider BC.GAME.


BitStarz is a crypto and fiat casino with a high reputation in crypto gambling. The platform differentiates itself as it offers quick payouts, sometimes under 15 minutes, and has a sign-up bonus of 100% of up to 1 BTC. The platform is registered in Curacao; however, because it has an off-shore license, some restrictions in specific countries apply. Even so, blackjack games are available to every player that can access the platform, and BitStarz is very appraised for its ability to accept major cryptos. Yet, BTC is one of the main tokens that’s widely used. In short, if you’re looking to get your blackjack game on BitStarz, start by depositing BTC to take advantage of the numerous bonuses.


Stake is a streamer-favorite casino that also accepts cryptocurrencies and has various blackjack games. Everything about the casino is very transparent; however, this leads to making users go through a KYC process before being able to withdraw their tokens. The good part is that Stake offers a 200% deposit bonus for deposits of up to $500. The bad part about it is that it requires a minimum of $100. However, Stake does have a wide variety of deposits, including DOGE and EOS, and also offers rapid withdrawals. Stake is your go-to platform if you want to play blackjack without making the process complicated.


What is the house edge for blackjack?

The edge is normally the share taken by the casino to allow players to gamble on their platform. In crypto blackjack, the edge can be as high as 5.5%.

What is the basic strategy for blackjack?

The basic strategy is to not hit cards between 17 and 21 and hit cards between 12 and 16. 11s and 10s can be double-downed. You also always have to split aces and 8s.

What are some blackjack tips?

Always play together with the table and never against them. One important tip is to check the dealer’s card before doubling down on an 11 or 10 because if the dealer has a 10 or 11, it’s best just to hit. Finally, never let your emotions get in the way of sticking to your strategy.

What is card counting?

Card counting is assigning a value to each card and increasing or decreasing your bet size if the deck is hot or cold.

Is card counting legal?

Card counting is legal, but it depends on what kind of blackjack shoe is used.

What are the risks of card counting?

The only risk is that you will be invited to leave the casino and be restricted from playing at the specific casino. This rarely happens with crypto blackjack.
