This is a fraudulent app,I have been trying to withdraw my funds for more than a month ,they have suspended my account saying there is suspicious activity from my account,that I should confirm my payment information,I have done that and this is the only message they keep sending,I have mined upto 0.01395459 worth of bitcoins by paying for cloud boost yet they don't want to release my earnings,please don't fall for their tricks,they are fraudulent.
