I didn't realize Hive had the ability to recover stolen coins. That's pretty cool.

His takes on Bitcoin prove to me how little he knows about the space in general. For all his other takes, I can point to some crypto that is exactly as he's describing, but his take on Bitcoin is wrong. Mining pools are not a centralization risk. They are groups of people working together and multiple times in the past when one pool gets too large, miners leave. Importantly, they leave because it's in their interest to leave.

I don't have the numbers to say so conclusively, but I'd guess that hash power has decentralized quite a bit due to the China ban. I'm also reading articles about small mining setups all over Africa helping to electrify rural villages with 3-5 ASICs making the setup economical.
