I mean this is crashing now, but at some point it will go back up. Blockchain technology will continue to make people in high places very mad. It's here to stay. Is there a lot of money in it right now for the stage it's in? Absolutely.
Blockchains are objectively a better system. If the government pulls a Napster on Bitcoin (and Blockchains), I hope they get whatever is coming to them. Napster -- it had its problems with fairness and ownership, and a reasonable case could be made as to why it hurt creative producers. But Bitcoin/Blockchains? Literally no case can be made as to why we have banks when we have Bitcoin. It helps everyone except the people in charge of the inferior systems.
For example, what happened with Slavery? There was a lot of old money in Slavery and at some point we had to be like "sorry guys, your system sucks". Of course, that ended with war. But at the end of the day, we are in a better system. I can proudly say "slavery is disgusting" without fear of being hurt by the government.
Today we live in a time of financial slavery. A time where certain people get to control our money and thus our means. When will we be able to say that "banks are disgusting"? I am waiting for that day.
