It shouldn’t be. Purchasing Bitcoins shouldn’t carry much of a transaction fee, and Bitcoin casinos also keep their service fees low. If they didn’t, there’d be little reason to use them. Players must just remember that the price of Bitcoin is always changing, so it is very likely that the funds you deposited into your casino account will not be worth the same amount when you withdraw. The good news is that the trend at the moment is for the value to increase, so it’s likely your Bitcoin will be worth more.
