If anyone thinks that Eth won't move to POS within a year, then go for the GPU. A 3090 should take almost a year to mine one Eth. (MSRP matters there.)
I started in February too and I knew the short timeline.
I plan on mining other coins too, but right now, if Eth goes away and miners all move to the other coins, that profitability will drop significantly. Hopefully something else pops up but there's definitely a "green" push in the crypto space.
It's not fully about ETH 2.0 and POS.
EIP 1559 Leads to base fee mechanicm change and eth burn (others think this will degrease mining profitability BUT also increase value of eth because ETH burn)
EIP 3554 is the most agressive change (early december) they increase ETH difficulty so it is almost impossible to profit by mining with GPU's if you dont have a lot of rigs. Small and home miners can switch the algorithm to other coins. like they say. ASIC miners will contiunue after this but GPU's going to "ice age".
After 3554 POS/eth2.0 merging starts and that going to be history how it effects to ETH markets.
And it is totally bullshit if someone think it not going to happen or they have some kind "gift" how they can mine ETH with 1 or 2 mining rig after EIP 3554.
Those who start mining in this year with new rig.... you are late already. You never get your money back by mining only ETH and you serioulsy need to make plans for the future.
almost every guy i know in industry says they mine ETH untill ice age (difficulty bomb effect) and then go back to ETC. Many have change their under 6GB cards to ETC about year ago. I also have 50% ETH 50% ETC ratio in my rigs. After ice age -> 100% ETC.
