I do not agree with your explanation for the following reasons:
It's not a matter of opinion so it's not important whether you agree with me or not. I just told you how things work with bonuses. It's information.
Unwanted Bonus: I did not intentionally claim any bonus. If your system defaults to "checked" or hides the option, it is misleading. I wanted to play with my own cash, not be locked by an 80x wagering requirement.
Be careful when you register on sites. Any sites, not just casinos. I have never unintentionally claimed a casino bonus that I don't want. You can do it as well. Even an unintentionally claimed bonus is a claimed bonus. Also, it's not "
my system." I am just explaining things.
Unfair Deduction Logic: You claimed that my "real money" was used first for bets. This is a predatory policy. If the bonus was active, my total balance was 1000 USDT (500 deposit + 500 bonus). When my balance grew to 950 USDT, it means I only "lost" 50 USDT from the peak, not 200 USDT of my principal.
You will have to read the bonus terms and conditions you agreed to and take it up with the casino if you think you were hard done-by. If those are the terms you agreed to, those are the rules that stand. Before you say: "I didn't agree to those rules!", you should know that you agreed to them when you registered an account at the casino.
