Special Bonus Bitcoin for Crypto Users

Before you sign up to a casino, make sure that you check out any available bitcoin promo code options. However, with the sheer variety of casino and sportsbook bonuses out there, you may get lost if you are a newbie.

There are two main reasons as to why online casinos offer such generous Bitcoin-related bonuses:

  • Making the signup process less stressful: Upon signing up, you will be given a variety of bonuses such as “Free Spins” on the slot machine games or an added boost to your casino deposit on casino games like poker or when you bet on sports. We’ll explain free spins and deposit bonuses below!
  • To make you keep coming back: Once you have played a couple of games, the casino will want you to become a regular customer. Bonuses act as huge incentives for users to keep coming back to the casino.

Traditionally online betting sites offer much better bonuses if the deposit is made via Bitcoin. For example, Bodog, the sister company of the popular online casino Bovada which operates outside the U.S., has a very generous Bitcoin Welcome Bonus for their users. They offer approximately $300 worth of BTC as a 100% bonus matching your initial Bitcoin deposit.


What are Bitcoin Bonuses?

Each Bitcoin casino has its own unique bonus offering. Let’s run down some of the most common bitcoin bonus options that are available in all these casinos.

Bitcoin Welcome Bonus

This is the bonus that you get when you immediately join a casino. More often than not, a welcome bonus is extremely generous as it is a way for them to rope in as many new users as possible. It is usually a 100% match or a doubling bonus on your first-time deposit. Meaning, if you add 0.5 BTC to your account, they will double it.

Some casinos tend to be extra generous by offering a bitcoin sports welcome bonus package, which will cover your first few deposits and add a larger bonus amount to your account. Bitcoin promo codes are available for all types of online gambling sites including poker rooms, sportsbooks, and casino games.

Deposit Bonus Funds

This is a bonus that you will receive every time you make a deposit in your casino account. While welcome bonuses are definitely nice, a savvy gambler will always choose a casino with alluring deposit bonuses. A deposit bonus basically means that every time you make a deposit into your account, you will get a bonus on top of it.

For example, BitStarz Casino offers four deposit bonuses:

  • The first deposit bonus is 150% up to 1 BTC + 180 free spins
  • The second deposit bonus is 50% up to 1 BTC
  • The third deposit bonus is 50% up to 2 BTC
  • The fourth deposit bonus is 100% up to 1 BTC

So, overall, we have a total deposit bonus of 5 BTC + 180 free spins.

Bitcoin Casino Free Spins

Free spins are one of the most common bonuses out there. The bitcoin free spin bonus is excellent because it exponentially increases your chances of winning big, without the risk of losing the money you’ve added to your account. Some casinos give out a large number of free spins during special occasions, while some give out free spins all day. Free spins refer to slot reel spins that you don’t have to pay for. So, if a casino offers you 50 free spins, it means that you can spin the reel 50 times without paying. Who doesn’t love to spin for free to earn potential rewards?

When using free spins at an online casino make sure to check out potential terms and conditions. Be aware free spins usually come with a set of requirements. Free spins have their limitations (as you can read below). With that said, the requirements for free spins are usually worth it.

Referral Bonus

The idea behind referral bonuses is pretty straightforward. You receive a bonus every single time you successfully invite a friend to join a casino. While some casinos set limits on the total number of referrals, others give you unlimited invites.

No Deposit Bonus

Some casinos will offer you a bonus even before you make a deposit. These bonuses are called “No Deposit Bonus,” and they aren’t that widely available. It can be thought of as a small preview of the casino.  Essentially, the casino gives a free bonus to your account, which will let you play some of the more popular games. In short, it gives you a brief tour of the casino experience.

Bonus Codes

A lot of casinos offer their users Bitcoin bonus code deals. Before making a deposit, simply pop in the bitcoin promo code and wait for the free bitcoin to be deposited into your account. Either you will get a bigger deposit bonus reward, or your bonus percentage will go up significantly.Bitcoin Bonuses

Bonus Bitcoins: What’s the Catch?

So, how easy is it to withdraw these bonuses at online casinos? Can you deposit your bitcoin and withdraw them immediately after you receive your bonus?

That will be a neat way to make money, right?

Unfortunately, it’s not that simple.

There are some requirements and conditions that you’ll need to fulfill before you can withdraw the bonuses at an online casino.

  1. Wagering

Each deposit bonus has a “wagering requirement” aka “rollover.” What this means is that a particular amount must be bet before the funds can be withdrawn. This amount is usually a multiple of your total deposit and the bonus.

Suppose you deposit 5 mBTC in a casino that offers a 100% deposit bonus with a 40x wagering requirement. The 5 mBTC deposit results in a 5 mBTC deposit bonus (100%) and you’ll need to wager 40*(5+5) = 400 mBTC. Only after you bet that much money, will you be able to withdraw whatever funds are intact. As always, and while bonus bitcoins are great to claim, only deposit and wager what you can afford to lose.

  1. Withdrawal Limits

You must read the terms and conditions of the casino to make sure that they don’t place any unnecessary limits on how much you can withdraw. Deposit bonuses won’t have a limit on how much you can win. However, there may be maximum withdrawal limits placed on free spins and no deposit bonuses.

  1. Time-Limit Restrictions

From the moment you receive your bonus, you will have a limited number of days remaining to meet your wagering requirement. Make sure to check the “terms and conditions,” to be aware of the time limit. It is usually between 7 days to a month.
