Hello,
I would like to start mining with three Antminer T21 (190Th) ($3625 per unit) and electricity cost 0.055 $/kWh.
But according to
https://smokinghopium.io it won't even pay for the machines themselves and will never be profitable. Do you have any thoughts or tips?
Sure. 1) I assume you can power them and cool them.
2) Next 570th using about 11kwatts an hour
does the following.
https://www.viabtc.com/4.65 cents a th or 570 x 4.65 cents = 26.50 usd a day
11 kwatts an hour is 264 kwatts a day or 264 x 5.5 cents = $14.52
thus you clear
26.50
-14.52
11.98 usd daily profit. If I were set them up and rack in the 11.98 usd a day and hodl hodl hodl that. Just cash the coin needed to pay your power
which is 14.52 usd a day.
I would mine to nicehash.com or viabtc.com
I have a refferal link to viabtc

https://www.viabtc.com/signup?I would help you set them up to viabtc.com
In theory you make money with your power cost. Assuming the room can be cooled off and you can handle the noise.
Basically smoking hopium is full of shit as 5.5 cents power cost is a solid money maker for the t21
