Amazing info!
Thank you philipma1957.
Unfortunately, The Merge will happen soon with Ethereum Consensus Mechanism so we won't be able to mine ETH with graphics cards anymore so in my humble opinion, buying graphics cards now is not a judicious investment decision on long term. When you look at all the other coins to mine, their daily volumes and market caps and sooooo tiny compared to ETH and most of them don't have real use cases (except to be an investment vehicle) that I'm pretty sure our mining profitability will drop enormously, I'm expecting maybe 50-80% drop.
This is why for the last 6 months, I have been studying Ubuntu Server and Rocket Pool documentations and started to run validators on the ETH beacon chain. It's the future, no doubt. It's crazy just on Rocket Pool, every day, big dogs or institutions (banks, insurance cies, hedge funds etc), are staking in average 2-3 millions USD of ETH value into the Rocket Pool protocol.
And and Nvidia have a lot to lose if eth goes full on pos.
I smell a hybrid system coming up.
