Wow, I didn't see that.
Actually, we're in a pretty good place for cryptology, at least I think we are. Ethereum in particular is very good now, and there will always be those who would seek to take advantage of these realities.
Just as there are those who want to make a quick profit, and without knowledge fall into scams easily.
I imagine that the amount of advertising that circulates on youtube is immense, but equally you should be able to review everything before publishing, because they expose many people to these scams.
