...This could kill all the crypto!...
LOL, not a chance in hell.
When it crashes and burns it'll just get more peops interested.Maybe, but it could also get "other people" interested in to ban just about everything. There are
many people who thinks that cryptocurrencies are beating the banks (for example), and they are enthusiastically "singing" POWER TO THE PEOPLE, but the truth is that governents, banks and big companies are already exploring Bitcoin and such. They don't need Bitcoin, Ethereum or something else, which is part of our "cryptoworld". Do you think that they don't have the funds and the power to make something similar (or even better) than Bitcoin, Ethereum, or... whatever?

How do you think you will react if you deposit $200Mn in a bank and get a response: "Thank you sir, but keep in mind that there is a chance for you to be robbed.". FUCK NO!
What I am trying to say with my not so rich english is that if you invest in a ICO and the initiator runs away with 10 BTC... that's a problem. But when you have gathered $200Mn from the "masses" and there are so important security flaws... that's a
BIG FUCKING PROBLEM. Then these "other people" have another
BIG excuse to get involved and guess what may happen next?
I think we have alot of ideas that agree but I am not quite grasping your post here. Even though you tried to encapsulate it. Lol
