Minutes. Traditional online casinos can take days to process some transactions. Most Bitcoin casinos will allow you to start gambling before they’ve even received all blockchain confirmations for your deposit, meaning you can deposit and be playing within minutes. When cashing out, you’ll see the money in your account an hour or two later, oftentimes even less than an hour. Be aware that some casinos do reserve the right to cash out larger amounts by using an installment method. Sometimes this is done as 10% of the withdrawal amount once a month for 10 months.
