After the end of Ethereum mining in September, there is nothing more to write about. An expensive RTX 4090 video card gives a profit of $ 1 when mining 2 or 3 coins, and most other video cards are unprofitable. And next year the forecasts are not the best.
I haven't finished writing the report until September (in the English version).
Either way, there would even be some interesting things to explore after the merge, but due to the rising cost of energy in Europe, it's complicated to do some interesting experiments.
