With ~90% of blocks solved by 10 pools, is Bitcoin really decentralized anymore?

its worked out that there is about 80exa of 'farms' and upto 60exa of smaller groups. which is why you see the hashrate peak at 140exa but drop to 80-90exa because hobby miners are jumping in and out at a whim.

Overall a great response thank you. And that quote right there ^ is exactly the kind of thing I was curious about.  Assuming accuracy, that means that really only about 60% (rough number at that 140exa) is actually these few big mines that I was referencing, and almost 40% is made up of much smaller. Assuming those numbers are correct, that paints a much better picture than what's easily assumed these days. Thank you again!

This is not a valid reasoning to call bitcoin is a centralized coin as 10 pools are getting 90% of new bitcoins. Firstly because the new coins generated are now negligible to what is already in circulation and it's 90% is further more divided into 10+ pools. A large amount of coins (40%) are held by a thousand addresses, which still is much decentralized that fiat money in the world.

People manipulate news on such potential centralization of bitcoin hashrates if some big pools make deal and work as a group. I don't know how they can accept such deal because it will potentially bring damages to all of us, including biggest-pools corporation. If one has been in crypto for long enough, back in 2017 and 2018, that one should well know there was many news on the bitcoin potential replay attacks due to their fear on hashrate centralization. How many years passed from that, 2 or 3 years and we have never witnessed a replay attacks on Bitcoin network. In the future, I believe there are more pools will join the the hashrates will be decentralized more.

I dont worry about this because pool is just gather place of miners to a strong calculate to "miner BTC". With Diff is very high now, individual miners cant mine BTC because they have a weak calclete though blocktime of BTC is 10 minute. This is reason why pool is born
