Some casinos lure users to their platforms with their deposit bonus, but once the user makes a deposit, they get stuck with their money. I guess the users are to blame here. Because they do not read the bonus terms carefully.
Sometimes to teach you, the best way is based on experience.
Suppose they are not reading the part of terms & conditions. I can understand, because is TLTR (To Long To Read) same for term & condition but that's just a stupidity and deserves to earn those due really lazy. Plus what's do u expect, get a bonus but without wagering most the time bonus will always have at least 40-50x the higher of the bonus % come with higher rules.
