The best proven miner is the ant miner s19pro
It specs at 110 th
watts at 3000
this miner specs at 360th
so 360/110 = 3.27 times better
this miner specs at 550 watts
3000/555 = 5.45 x better watts.
so 5.45 x 3.27 = 17.8 times better then the best known miner.
bitmain asks 2675
this company asks 4500
forget shipping or taxes why would you sell an item 17.8 x better then you nearest competitor
at only 1.68 x the price? the answer is you would not you would ask a correct price or you simply are hawking a product that does not exist .
this is like buying a good gas mileage car that claims it gets 300 miles to the gallon and it costs only 5000 dollars.
You would know it has to be a fake.
These sellers pop up every one or two years. hoping to get a few fools to buy in.
Do not be a fool.
