That's the only good thing that came out of that nonsense. Rich people getting scammed. Just wished it wasn't also your dear uncle Sam who now lost his life savings to a fucking nazi ape.
But also as 'just' a technology, it's extremely inefficient, it is prone to fraud and unreliable at best. There is no use case beyond scamming really.
Maybe tell blockchain to stop hogging our electricity and water supply and I'll look into how this completely unnecessary thing works. At this point I may as well watch an M night Shyamalan movie. Just as unnecessary and densely stupid.
