Skeptical about skeptics
Correct but nowhere near as much as you might think.My understanding, and I am not an expert, is that mining bitcoin plays a role in verifying and recording bitcoin transactions, so continued mining is necessary to the utility of bitcoin.
You would only need a few thousand PCs around the world dedicated to mining to verify transactions and keep the blockchain going because bitcoin can only store a few thousand transactions per block. The rest of it is just super computers competing with each other to get the next block and wasting an incredible amount of energy in the process.
