I am asking this on behalf of a friend, is 580 8gb still worth buying in 2022 for long term crypto mining? The rx580s are the cheapest around him like 150-180$ per card, what do you think pro miners?.. He said he has cheap electricity bill.
580 8gb have been mining for 3-4 years. In my country, there are a lot of offers for 150-160 dollars.
To buy these video cards, you need to carefully check this. If you want to buy them, then do it after the end of ethereum mining, when there will be much more offers and prices will be much lower. For the remaining 20-25 days of Ethereum mining, you will not get a big profit.
I would also strongly suggest the same also,as when Ethereum mining will go away these cards cannot do that much other algos except ETC which most people will flock into it,we already have 565 T difficulty in ETC network while before the news of Ethereum mining it was maximum of 382 T,it shows people have already migrated here,beside this algo the Rx versions can mine RVN but at the cost of greatly heating the cards,so most probably the price after the first half of September will be like 50-60 dollars for a card which would makes sense to buy them then.
Keep in mind though as you can use your ETChash to be used at unmineable website where you can choose any coin to mine,you only will get slightly decreased mining rewards daily,so if the price will fall in the second half of September get these cards if you have cheap electricity because right now one such card can make you 0.035 LTC through unmineable mining pool and six of them can make you 0.20 LTC daily which in USD is not much but in crypto 0.20 LTC is a good amount to be mined daily.
