ps: I'm wondering how pools are going to divide 1 sat to multiple miners during 2136-2140.
The block subsidy might only be 1 sat, but there are still all the fees to consider, which will result in a block reward far higher than a single sat and easily divided between multiple participants.
Every miner, investor has own limit and when we have a majority of miners reach their limits, we likely witness a miner capitulation.
That's not how it works. There will not be a mass capitulation like that. If an individual miner reaches their limit and turns off all their equipment, then by doing so they make mining easier and therefore more profitable for every other miner they leave behind. It's a self correcting process.
