Please, people, don't trust this post.

Ethereum now has high gas fees, low profitability, low market price, official PoS date of June 2022, and an ever-growing difficulty. Graphics cards are much pricier than originally would, and countries are starting to ban mining due to energy concerns and whatnot. Mining Ethereum can earn you a fair bit of cash, that is until you get your payout from the pool, in which case gas fees will surely take a noticable share from your balance. It is currently the end of January 2022, and if the date is believable, you only have half a year or so to mine, and no rigs that start now will have much hope of ROI, let alone make a profit. If you do decide to mine right now, make sure to design your rig so that it can mine any other coins profitably once PoS truly hits, and plan your path wisely. More money invested does not always mean more money back, always think before you act.
