150 ? nice
But how much time did it take?
I think nobody would mind having his account limited because he won too much money

Unfortunately, betting steam loses you accounts really quickly. Also, tennis is a minor focus for most books so they really don't have much tolerance for losing money on it. You can mix things up with bets on more popular sports, but steam is a bit of a giveaway - most books have automated tools that notice when there is big market movements, and which customer repeatedly leaps on them.
