Hello,
after how long they released your bitcoin? and, you had to do some other things for let them release your money (contacted them by email or just the procedure for withdraw?)... how much they were holding for you?
Regards
Apprantly OP contacted them on reddit to get their bitcoins released.
Anyways, I don't think that ti's a good idea to invest in any of their plans at the moment. Even though they seem to be a registered merchant within China, it is still unclear when I did my personal research whether they are actually mining to get these profits or just running a ponzi scheme.
Plus, the crypto conditions in China is pretty volatile and you don't know what the Chinese government is going to do next. Your funds are not going to be safe with them. Their interest rate isn't even that good.
If China tightens up their bitcoin regulations, then you could potentially be out of your funds.
