anyway, hashnest provides a cheap BTC cloud mining scheme. But it will make a cheap plan much better if their service is improved: e.g. use real hashrate instead of faking, improve the poor English, and answer the support damn support request (I submitted a request on September 3, and until now it is still "solving"!!!)
All we can do - is wait, and hope for the best 
But main problem for me - is the Traiding interface. It's horrible compare to CEX.io.
I hope when they open trades, they will rebuild it
p.s
Finally 5min and 15min values comes to normal.
