I agree that crypto-currency is dangerous and that a lot of people are completely unaware of the risks involved. There 100% are some dodgy characters involved in publishing tokens, but there are some completely genuine people involved too.
There is a lot more to it than people perhaps think and I feel statements like those I queried perhaps come from fear, misunderstanding and misinformation. Which can be dangerous in itself.
What stood out to me though was making such bold statements followed directly by stating a complete ignorance of how they work. People are of course free to dislike something, I just feel perhaps it would be better to build some level of knowledge of something before judging it.
Not trying to sound preachy or that I'm judging anyone, so apologies if it reads that way.
