Also there are various specific cryptos that are easier or harder to mine. I believe monero is quite easy and bitcoin is more difficult, for example. I swear I’m not a cryptobro, I’m just a computer nerd who has been asked to explain it so many times that I have an okay understanding. Plus I had a CS teacher who was super into crypto and did a few lectures on it. You are generally correct, though. Also apologies for incoherence. My brain is not braining so well today.
