This one suggests that mining will be a new kind of business.
There are no new coins for mining yet, so I expect a big sale after the transition of Ethereum mining to the POS algorithm
There's good coin candidates after ETH PoS for GPU miners. I am thinking about Ergo, Ravencoin or EthereumClassic.
I think PoW is here to stay because no consensus mechanism is perfect, you got pros and cons. So investing in these coins mentioned above are simply investment vehicles and I don't see why they will disappear. Furthermore, Ergo has smart contracts like Ethereum so it has a real usage!
I was looking at the prices on Ebay for the RTX 3070 graphics card and surprisingly they all increase a little. I bought a RTX 3070 at 1,400 CAD a week ago now I cannot find that same RTX 3070 model under 1,600 CAD.
LHR versions have a lower hashrate on Ethereum and Ethereum classics.
Ergo, Ravencoin and EthereumClassic will not be able to accept such a huge number of graphics cards.
Perhaps the prices for video cards have grown due to the rise in the price of ethereum, but the profit in mining is falling.
Ho god it's my nightmare to accidentally buy a LHR graphics card. No I never buy a Low Hash Rate GPU and I tripple check on the product page of the GPU. It will be mentioned if it's a LHR GPU and it's only the new GPUs. I was thinking that most probably a lot of beginners will make the mistake of buying LHR GPU, it sucks really. I started to notice that there's more and more RTX 3070 Ti (the Ti version is LHR) and less and less RTX 3070.
I bought this RTX 3070 last time on Ebay at CAD 1400 ( ≈ USD 1,115)

and surprisingly I got 62.37 MH on ETH for 105 W which is the best power to hash rate ratio I have for a GPU. 62.37 / 105 = 0.594 or 59 % efficiency!!!
I use HiveOS for my mining platform, T-Rex for the mining software and Hiveon pool for my mining pool. Here's the overclock on that GPU: Core: 1100 ; Mem: 2600 ; PL: 125. It's been a week now and it's ultra stable.
Concerning the EIP 1559, I personally didn't lose any revenue. I make a little less ETH per day but the price increase offset that.
