Can you still build mining rigs with 6gb GPUs like gtx 1660s in 2022? For how long can this graphic cards keep up with mining? I'm sure they are better option over rx580 4gb, what do you think?
yes for sure but eth will switch to pos at june 22, you have less option after that and many gpu miner will dumping their gpu before or after that, million of used gpu hit market
and pc gamer will got they want after that, some miner will mine on other algo / coins, so sad to say this
One of the ways in which devs can combat asics is by using memory capacity intensive algos, so the higher your memory capacity is the more options you'll have.
And yes you should be fine for the two years at least if eth does not succeed with the POS transition, google eth DAG calculator for more info.
There are certain inherent flaws in POS compared to POW when it comes to consensus but eth has some of the best brains behind it.
Been hearing ETH is going POS since 2017 and yet here we are.
Don't get me wrong, I wish them luck and really hope they will pull off the POS transition and hope they pull it properly.
Because if they don't its going to be the biggest rocket ship explosion ever.
