New Yorkers haven't been allowed to trade on Bitfinex since 2017. That's when they updated their terms to discriminate against US entities. If US persons are illegally and fraudulently trading on Bitfinex, that does not give any US authority jurisdiction over Bitfinex. How grandiose.

I can only guess that you are not familiar with the technical jargon.
Your pleading strikes me as potentially disingenuous, but I will speak earnestly in spite of that.
You will or (will not) be a "crypto fan" after you've absorbed enough technical literature to make your own judgement about what is happening. If you have the time, I recommend starting with the Bitcoin and Ethereum whitepapers.
The list that was provided was of abstract ideas without stating a specific market — any market.
The ethereum apps you linked to might be interesting from a technological standpoint, but they don’t really add value — they just are [banking function] or [payment function] with cryptocurrency.
The most generous example that I can come up with is that crypto makes it possible to displace PayPal and similar payment processing middlemen, but I’m not sure most people (outside of a few legal outliers) actually want those middlemen replaced. So even then, the issue isn’t that crypto is so great, it’s just that the fiat currency system is slightly inefficient while being incredibly fixable.
I guess I just don’t see the demand in the marketplace for what crypto is providing the supply for (other than as a tool for speculation... it’s really good at that).
