> ... once you subtract all the plainly unethical transfers, securities-laws-runarounds, pump and dumps, and wash trading, how much of a business is left? Coinbase, a HN unicorn, probably knows? Their KYC/AML is top notch (which is a PITA for honest people btw). They know how many USD actually entered and whom send them. They may have had insiders accused of pump and dumping but AFAIK Coinbase hasn't been accused of pump and dump. Coinbase has now been chosen by BlackRock to keep the Bitcoin backing the BlackRock ETF in custody: I take it if Bitcoin ETFs are accepted, and if BlackRock and Amundi and I don't now who else start launching Bitcoin ETF, we may begin to see what's left? Someone else who may know: that weird dude who is behind MSTR: he basically bought 158 000 Bitcoins at an average price of $29 K USD and he plans to buy much more. (if you want to long or short Bitcoin, you can do so on the MSTR stock for it basically follows the ups and downs of Bitcoin). What's left, for all we know, could be much more than what's already in (I've got no crystall ball though). The one thing that I'm sure of is that it's not all fraudulent. For example an estimated 25% of all people in argentina have cryptocurrencies: I doubt one person out of every four there is a criminal!? Switzerland: if there's one country where its citizens really don't strike me as criminals it's Switzerland. 20%+ people owning cryptocurrencies there. I can understand the "there are no use cases besides speculation" argument. But I cannot understand the "all the people using cryptocurrencies are criminal" one. When you've got several countries in the world where at least one out of every five person did at least try cryptocurrencies, there is something.
