Are you saying they are? Even if they are, it's beside the point; they are paying for massive amounts of advertising in countries that have functional banking systems.
I think everything crypto companies do is beside the point. Satoshi created a system where you can be self-sovereign and not have to trust anyone. And now these companies want you to forget about all that silly trustlessness, and trust them, so they can take a cut of your money. So you should, almost tautologically, ignore anything they say on TV. By a similar principle, you shouldn't base your opinion of gold's value on those cash4gold commercials.
