Ok, thx Do you know a good miner to buy then?
Easiest to find:
Bitmain's s9 or T9
Canaan Creative's Avalon 741
The one LEGITIMATE new kid on the block and for now at least harder to get hold of:
Ebang company's ebit e9 6.8THs miner
Yes Hotmine.io is also making miner upgrade kits using Bitfury's 16nm chips. Looks good, folks are happy with them but it IS an upgrade KIT to resurrect s1-s5 miners chassis.
That is all there are for current miner makers with real miners IN PRODUCTION. Period.
When buying any of these new miners ONLY BUT DIRECT FROM THE MANUFACTURER!
NONE of them have distributors so if someone claims to be an Authorized seller/reseller of those companies they are LYING.
When it comes to outrageous speeds with unheard of low power -- ALL the above miners are state-of the-art and their performance will not be exceed for at least a couple more years.
