21bit Casino

21bit is a crypto-friendly online casino with more than 3,000 games, a wide range of bonuses and a stylish user interface. A company based in Curaçao launched the site in 2022, and it is fully licensed and regulated by the government of Curaçao. The site may be new to the market, but the parent company is vastly experienced, offering a large suite of popular crypto casinos, and 21bit is one of the jewels in its crown.

Our 21bit Casino review explains why this is one of the best crypto casino sites available. We will discuss the five-part welcome bonus, the weekly reload bonus, the additional promos and the detailed rewards program. You will also learn more about the quick payouts, the game quality and the variety on offer, so continue reading for a detailed 21bit review.

The regular welcome bonus at 21bit Casino is worth up to 0.0333 BTC, plus 0.333 BTC. It is divided into five parts:

• 100% first deposit bonus up to 0.006 BTC, plus 50 free spins
• 75% second deposit bonus up to 0.006 BTC, plus 50 free spins
• 100% third deposit bonus up to 0.006 BTC, plus 50 free spins
• 125% fourth deposit bonus up to 0.006 BTC, plus 50 free spins
• 150% fifth deposit bonus up to 0.006 BTC, plus 50 free spins

You need to make a minimum deposit of 0.0005 BTC to claim each part of the bonus. The free spins are available on Aztec Magic Deluxe, and they will be credits in two batches of 25 spins per day. All winnings from the free spins will be paid in bonus credits. This is far from being the best bitcoin casino bonus but for the casual player it might still be useful.

Your bonus credits will have a 45x wagering requirement, and you will be given seven days to satisfy it. Most slots count 100% towards completing the requirements, but there are around 200 excluded games. Table games and live dealer games do not count towards the wagering requirements.

"High-roller" option

There is also a "high-roller" package (their definition of a high roller is pretty generous), which is divided into five parts too:

• 75% first deposit bonus up to 0.03 BTC, plus 50 free spins
• 100% second deposit bonus up to 0.03 BTC, plus 50 free spins
• 125% third deposit bonus up to 0.03 BTC, plus 50 free spins
• 125% fourth deposit bonus up to 0.03 BTC, plus 50 free spins
• 150% fifth deposit bonus up to 0.03 BTC, plus 50 free spins

A minimum deposit of BTC 0.0068 will be required for this bonus. The free spins will be available on Primal Wilderness. Winnings from those spins will have a 25x wagering requirement, whereas the deposit match bonus funds will have the standard 45x wagering requirement.

Payments are quick and simple at 21bit Casino. It does not charge any banking fees, and you can use a wide variety of cryptocurrencies. Players that do not hold any crypto can use a fiat-based payment option to buy some on the site.

Deposits

21bit accepts deposits via Bitcoin, Bitcoin Cash, Ether, Litecoin, Dogecoin, USDT, XRP, ADA, TRON and BNB. It has a minimum deposit of 0.0001 BTC, 0.01 ETH, 5 USDT or similar amounts in other currencies, and there are no upper limits or deposit fees.

If you use Bitcoin, you can withdraw between 0.002-0.4 BTC. The limits are just 20 USDT to 4,000 USDT per transaction via the leading stablecoin, but they go up to 0.1 ETH to 20 ETH if you use Ether, so that should be suitable for high-rollers.
