You deposited €7000 and only won €300, yet the casino blocked your account? usually, the casino blocks the account and performs a verification if the player wins a very large amount. that seems strange to me.
Hello! I don't see anything wrong with the bets the user makes. If the bet is accepted and not declined, then the player has every right to be worried if the site unexpectedly freezes his account or his money.... I know many players who bet huge amounts on low odds and such bets will be seen more and more often.
