Aren't half of monero being mined by malware? lmao
Bitcoin has a mining centralization problem too buddy, it's a vulnerability to all PoW coins. Monero wasn't 51% attacked, it was about 37% at peak and was a selfish mining attack. If just two BTC pools colluded they could perform the same attack https://hashrateindex.com/hashrate/pools
Bitcoins mining has a larger problem due to ASICS. Only one manufacturer currently makes the most competitive chips to mine Bitcoin which is a major supply chain centralization factor and a backdoor vulnerability. Monero uses RandomX which makes all CPUs roughly as efficient as each other. You could mine on a 20 year old laptop, a VPS or a dedicated server.

Yeah it's likely a big portion is. Not moral but it's a consequence of RandomX. It's actually good for decentralization oddly enough. What's the point?
