If you win consistently, without breaking the rules of the bookmaker, without betting on fixed matches, the bookmaker will not block your account. But keep in mind, according to statistics, only 2-3% of all bettors are able to win regularly (but not every time) and stay in positive territory for a long distance. They become professionals here, each working out his own profitable strategy. All the rest players, for various reasons (inability to cope with nerves, unwillingness to conduct a serious analysis of matches, lack of a coherent strategy, passion for express bets, etc.), are not capable of this. The bookmaker can block the user if he suspects him of foul play.
