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....
