Talking about actual wagering requirements is already on the casino website itself from the existing terms and conditions, after all, before betting there's nothing wrong with reading the casino requirements so you don't get stuck with withdrawal problems that will be asked for wagering requirements with a certain nominal.
Some casinos do not have the same wagering requirements as most casinos, which is why we are sometimes surprised in the end. However, if it's stated in the rules, then we can't consider them a bad casino. It's our responsibility to read and understand the terms of service (TOS). Ultimately, it depends on the satisfaction of the gamblers. If we're not satisfied with a particular casino, we are free to try other casinos with TOS that are convenient for us to follow.
Let us not make things complicated, you like a casino, you stay, you hate it the you leave.
Every casinos has it own requirements and many gamblers do not know this or maybe pay less attention to this aspect, some of this requirements were clearly stated in their TOS, nothing can change it because they put them there on purpose, gamblers always made a complain rue to their non compliance to these regulations and terms, ones you discover you can't cope anymore using a casino, you're free to go and try out others.
