Base on the data that you provide, you bought hashrate USD 147.23 per TH/s from MinerGate and get an average result 0.0000277 BTC per TH/s after fees everyday. Compare to HasFlare today's 0.0001352 BTC per TH/s after fees, I will say you choose the wrong cloud mining compay.
Daily maintenance fee is feixed to $2.452924.
They simply cheat you with the amount btc mined ... the BTC amount must be 3-4 times higher ...
They have sold me 7.5 TH/s but in reality they give me 2 TH/s ( my contract of 7.5 TH/s is mining daily 0.0002 when it should be about 0.0009)...
The problems is not the fee the problem is real TH/S. they also not show the statistics just add you 0,0002 mined rest $2.452924 fee for maintenance and you see you total mined....
Original post also updated.
So you are saying they charge too much for maintenance and they do not even give what you paid for. That is not good and I am sorry you lost so much but thank you for telling people so others do not have it happen to them...
