I have read all of your responses regarding this matter and it seems that everyone agrees that a x5 wagering requirement for withdrewing your own deposit and no bonus is simply unacceptable.
The casino is able to put whatever requirements they wish on their bonuses and deposits. We don't have to agree with them and we can choose to play elsewhere, but IMO a 5x wager requirement on a deposit is very bad for players. They're not scamming by having these terms, they're just a casino that's very hard to win on with these terms.
