I think many of them turned shitcoiners.

It’s true that “addresses holding >= 1 BTC” ≠ “people holding >= 1 BTC”, but it goes both ways. Just as one person could have 10 different addresses with >= 1 BTC, there could be a lot of people with >= 1 BTC sitting in exchange wallets. Yeah, I know, in which case they don’t *really* have >=1 BTC, but I think it’s valid enough for stats. Anyway, absent any better data, I think it’s reasonable to assume that the two more or less balance each other out — number of addresses holding >= 1 BTC is a reasonable approximation. In the grand scheme of things, it’s probably a lot closer to 1M than 10M and probably closer to 1M than 100K, and given that there’s 8B people in the world and only 21M BTC to be had, I think that’s accurate enough.
