why is that sad? they make a product you want ....
Almost every successful product based business grows this way. If people did not buy Bitmain miners they would not have the money to innovate and bring out newer, faster, more efficient miners. And you can replace the word miners with widgets and Bitmain with any company building cutting edge products. Tesla has done the exact same thing as have 100's of brands we buy and use every day.
Bitmain has a lot of faults, like there deplorable repair system. But it's a well run business in most respects.
It's sad that they sell junk and don't warranty it worth a damn.
And we don't payf or them to invent, I'm fairly certain they keep a miner for every one or two they sell which is dumped into their farms. have you seen how big they are? we bank roll their mining.
Which would be okay if the hardware they were releasing was worthy and reliable.
Hashnest and the gear never breaks. pay 7 cents for power and use of their psu.
To compete against this you need 5 cent power with no breakdowns. or 3 cent power with breakdowns.
really not much choice to go past mining at hashnest.
I think they just haven't squeezed all of the juice out of hashnest S7's so they are lowering the fees. Otherwise they would face huge amount of S7's being redeemed. As long as S7's are in their hands, they earn transaction and maintenance fees.
Or an even worse suspicion: they simply don't have that many S7's to back up the amount represented on hashnest. it could be hashrate created from nowhere, or from S9's.
