Mining with Antminer T21

[nivelety]

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.

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

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

Another approach would be buying only 2 T21s, and using the rest of money ($3625 at the time of his post), for two T21s his daily bill would be $17.6 which means he has enough to pay 205 days without having to cash out BTC, this approach works as a hedge against price drops, because if the price of BTC drops and he has no side cash to pay the power bill, it would mean that in some months/weeks he may be forced to sell his entire BTC earnings to cover the power bill.

Obviously, you could say, why not buy only 1 miner and use the rest of the money for power, that would also be valid, the above is just to explain the idea of hedging your investment to account for power bills paid during times when BTC is doing terribly.
