Sure ethically they where "right" and not illegal from a EU POV, but still illegal in the country they happened.
Besides that most other stories are people getting rich by high-risk speculative investments. But the problem with mass investments into high-risk speculative investments is that they tend to create bubbles which can destabilize the economy, so not really that grate either.
There are a lot of good use-cases for the technology behind crypto currencies.
But much of the current crypto currency landscape is not grate a lot bubbles, a lot pyramid schemes and scams, a lot of things which conflict with money laundering regulations. And many other problems.
I'm fully sure that the related technology (blockchain etc.) will have a future, I'm not sure about crypto currencies like we have them now.
There's an argument that if you want to eradicate a great deal of crime, just change the color of your money, and offer a 1-1 exchange at the bank. An awful lot of dirty money would have to surface, and can be asked about.
*other currencies are available.
really, what is the scam? Cause if u invested in bitcoin 10 yrs ago, u could trade that now for a new car without a sweat. They were right. The cryptobros were right that hedge funds would join the game. And they will be right when you can trade that bitcoin for a house while the iphone sits in history.
It's not.

A great insight would take into account more prominent cryptocurrencies and 3rd world countries but you don't throw pearls before swines.
And inflation isn't the only criteria of stability for a government.
But you're correct about pearls before swine though.
