I hate to say this, but this is the same thing that happened to Coinbooster.io. I understand that this is what happens when you have a shit ton of people trying to make hundreds of withdrawals a day, but this definitely does not sit well with anyone that has been on coinbooster.

The admin there said he would fix it over and over, and then he just disappeared. His reply in the forums before he disappeared, to everyone having the error? "Just keep trying, or try in a few minutes."
