So far I was very satisfied about CryptoTab. They have a low withdraw minimum amount and they paid out very fast.I have more than 0.0008 BTC balance now and I did a withdrawal request a week ago. But still it is not paid out. Normally you never have to wait so long and I made lots of successful withdrawals in the past. So I think it’s scam now indeed, just like other people say now. I’m happy I never paid or invested money to buy more Hashrates.
