Payments, Safety and Security

4Grinz Casino is a 100% bitcoin casino and one should have a bitcoin wallet for deposits and withdrawals. The bitcoin wallets recommended by the casino are Cubits, Bitfinex, BitQuick and CoinMama. You can begin gaming as soon as you make a deposit of 1mBTC/0.001BTC. Withdrawals can be done instantly and the minimum amount that can be withdrawn is set at 60mBTC/0.060 BTC. Due to security reasons large number of bitcoins cannot be stored in a server, so withdrawals of high amounts (e.g. 50 bitcoins and above) will be paid out as installments at 10 percent or above each time for a specific period until the whole amount is delivered.

As all operations are done through BitCoin there is no question of whether your financial data will be compromised, moreover 4Grinz is well protected with the latest SSL encryption standards. All games are proven fair by iTechLab, an independent testing agency.


4Grinz can be really proud of their friendly and systematic customer support team which offers assistance via email ([email protected]) and live chats 24×7 which more than makes up for the lack of phone support.


4Grinz likes to get things done as fast as possible, be it their quick registration process with no membership fee or their instant withdrawal support. The no strings attached approach is another highlight, with a Coin Back reward system that isn’t chained with any wagering requirements. Not to mention their active customer support team that works round the clock and excellent security. All these make 4Grinz one of a kind in the online casino business.
