Dude, you should not be going to some site to spend money in order to reach some VIP level. You should gamble for fun.

Also, I'm with Stake on this one. They cannot give you 0.5 BTC bonus because you've lost 0.68.

I believe that bonuses depend on many factors like your wagered amount, recent activity, bonuses received so far etc. I'm the player on Stake as well and I've never received my Bronze VIP bonus because I've reached it like a half a year ago when they didn't offer bonuses for Bronze.

Now, chill.
