Of course not. I've never stated Bitcoin was a PoS coin. What I've meant is that big companies can acquire a large portion of the network's hashrate by establishing mining farms. They'll be limited to amount of money they can spend on ASIC hardware, though. As long neither institutions nor governments are able to influence miners' decisions on the Blockchain, there should be nothing to worry about.

PoW coins by far, are the most decentralized and censorship-resistant ones on the industry. You can see why "shitcoins" like ETH and SOL have been compromised by wealthy people (corporations. whales, exchanges, etc). That's why they'll eventually die (or become easier to regulate by the government) in the long run. With LTC now experiencing increased interest due to the spot ETF hype, we can expect market prices to go all the way to the moon. The comeback is inevitable. Hopefully, it will stay decentralized and censorship-resistant for generations.
