I have a friend who still mines on GPUs and just uses nicehash as the pool and auto converts to BTC or ETH after mining the most profitable "coin" for that algorithm. I would suggest doing this. It auto picks the most profitable coin for that algorithm you are mining and then at the end of the day converts to whatever crypto you would like. Mining at this stage in the game i would say is a long game. The times of profiting and ROI in few months is def gone i feel. Also with staking i feel it is easier to make similar or better profits. DEX's and DeFi is still in such an early stage. One of my favorites is a project called Horizon Protocol with synthetic assets and huge APRs for staking all run off the BNB chain. Sorry to get off topic. It has been quite some time since i mined. I found the electric was crazy as i was renting a datacenter with like 30 miners from AntMiner company at the time. Whats funny is it was such a long wait from preorder to delivery when they were delivered and in hand the miners themself were worth about 10x. Year or so later they were almost obsolete and slow compared to newer super ones. Almost better to just get the equipment on preorder and flip in hand lol. But also i found it almost better to take whatever money you are going to invest in mining and put it in said coin as eth or whatever and leave it be. Just some honest tips, hardfalls and opinions from a guy who mined for years, years ago. Hope that helps. Also use lots of math and see your ROI, electric usage ect. Have to have the gut and funds to wether times like now when coins are lower and mining difficulty high. Again its more of a long game. If you can mine and hold for the next 5 years ya you will probably most certainly win
Nicehash gives a few cents of profit from each video card, but only if you have inexpensive electricity. It's pointless to use new video cards for this. If your friend has already paid off his investment a long time ago, then he may continue mining for a while. But the hashrate is falling for many coins, so buying coins is now more profitable.
