The withdrawal fee must be in platform currency, and you have to mine if it is not enough I bought a mining machine, but it did not move at all. After two days, the remaining time only decreased by two hours! According to the rules, it would mine a few coins every day, but it is only 0.1 now! And it comes to deadline, the pledged assets can't return back. I have been tricked! Platforms that don't follow the rules are very pitted. Don't manage money on this platform!
