Your anwsers doesn't make sence at all .
"Hashrate per unit of energy expended is significantly higher for RandomX. That's why the hashrate and difficulty are increasing. "
So thats why we have increasing of the people who mine? Do you see any working logic in that sentence?
I think verry soon will be clear that there is increase of the mining power because of the cloud VPS services , not sure for how long.
So you mean that the hashrate after they switch to RandomX algo is increased? Or are you talking about the network hashrate?
If you are talking about the hashrate increased it means that the mining performance is increased with this new algo so all miners are also affected so difficulty increases because all people who mine XMR has a little improvement on their rigs so more network hashrate increase and difficulty increase.
But if you are talking about a network hashrate but no little improvements in your mining rigs the possible can be the reason maybe there are many people mining XMR with CPU(Newcomers) who enter mining with their own PCs.
Possible that someone abusing the free cloud VPS to mine XMR just what I heard from other forums that they can make multiple VPS accounts with free balance. Or it's because of marketing who promote cryptotab who offering to mine directly with their CPU through the browser.
