How do you feel cheated no site or wallet has ever forced someone to gamble and with the price increasing that should be a lesson for all of you to not gamble and better to save you are simply feeding more value to the casinos they still accept only bitcoin so it doesn't make any difference to them
I agree, if you think bitcoins prices would go up then why did you even gamble with your btc? That is your own choice and that is your own and you cannot blame this on anyone. If you want to gamble then gamble using fiat and not your bitcoins. There are plenty of other gambling sites that accept fiat anyway, in fact there are 10 times the number of fiat casinos than bitcoin casinos.
