an interesting additional data point is https://www.chainalysis.com/blog/bitcoin-market-data-exchang... — while i don't trust chainalysis in general i suspect that they are probably telling the truth when they say

> As of June 2020, roughly 18.6 million Bitcoin has been mined. (...) Another 20% hasn’t moved from its current set of addresses in five years or longer. We consider this lost Bitcoin.

which suggests that the amount of lost bitcoin is at most 20% rather than the 90% or 95% i was suggesting

also, in talking about its historical impacts, it seems like probably we really should mention ransomware and darknet markets for, mostly, illegal drugs
