Sorry friend, but you are pretty misinformed.
BTC mining operations are extremely concentrated with mining companies, just as I said. Yes, there are large pools, but the majority of the hashrate is coming from just 5 companies, all of which are in China. They control 49% of the global hashrate. China overall controls 65% of the global hashrate. The remaining 35% are mainly spread across the US, Russia and Kazahkstan, as well as Iran. Some of those 35% are pools, not all of it.

It has become a real problem.
PoS may lead to concentration in some cases, but it is not the case with Ethereum, which the statistics for the ETH2 Beacon Chain clearly show. There are literally thousands of decentralized pools to create validator nodes, and unlike ETH's mining operation, which suffers the exact same issue as BTC (concentration, primarily China), the ETH2 validator pools on the beacon chain are very decentralized.
We can argue over the details all day long, and I am sure we will each find correct arguments. But saying that Bitcoin is way more secure than other chains is an outdated myth. Bitcoiners, especially the maximalist types, need to finally open their eyes.
