You should mention the rollover requirement on the depo bonus.
The wagering requirements have a minimum of 25 times the amount of bonus and the real money sum contributing to the bonus figure.
So, if a user makes a 0.5BTC depo they get 1 btc to play with, but they have to wager 25btc.
And another thing important to mention is the max win from the no depo bonus:
The maximum amount of money to be won from a no deposit free spin bonus and gameplay with mentioned bonus funds is 50 EUR or any other currency equivalent. Any winnings exceeding 50 EUR without making a real money deposit will be void and will be kept by BetCoCo
I don't like at all the fact that wins bigger than $250 require KYC for withdraw, is like searching for a excuse to not allow users to withdraw.
The reason why players needs to be KYCd to withdraw big amounts, is to protect ourselves from AML (Anti Money Laundering) claims from regulators.
