But the chip shortage is real and not going away.
Yes, the shortage of hardware (due to several multiplicative reasons) is keeping mining profitable. I can see it staying this way for the rest of the year.... but getting hardware is tough at any price right now.
I enter newegg shuffles and buy when they come in. So far they have sold me
Asus tuf 3070
Asus strix amd 6700 xt
Msi Ultimate 6800 xt
Evga Rtx 3060 3657-kr
Msi Suprim Rtx 3070
Evga Rtx 3070 3755-kr
Evga Rtx 3090 3987-kr
I entered every one but 1 from Jan 23 to now 6 of 30+ were a hit.
The cards came to about 2100 + 700 + 880 + 430 + 1200 + 900 +895 + 830
or say 7935 usd all this year.
they hash about 400mh eth and 40 mh octopus
thus it is 44 usd + 2 = 46 usd for about 900 watts
compare to an s19pro 13k if lucky burns 3300 watts and makes about 40 usd before power
So in 200 days with luck I earn 9200 and spend 4320kwatts at 20 cents = 864
9200- 864 = 8336 which is about 400 ahead and all that gear by Nov 26 2021
