I played on Bitcasino.io and I told myself never more. I didn't play with that huge amount I am not that rich but I have seen that they are not that fair casino. Support is so rough and they do not respect players and yeah they do not know what wager is lol. I remember they told me I need to lose my coins to get a bonus. Games start to crash when you start winning and you have to reload the page. I do not trust this casino. I am sorry for your losses that is not a small amount.
