I don't understand how people make these statements. None is a very strong word, just need one counter example to disprove his argument.

I can name a lot of counterexamples, however most of them are illegal under US federal law so it's a bit of a moot point.

There are legal counterexamples, but the majority that come to mind are equally well-served with fiat. If you ask me to come up with a good, legal reason to hold cryptocurrency, I may well tell you that there is none even if there are a few marginal situations that justify it.

See PurpleRamen's comment above. Blockchain != cryptocurrency.

For blockchain, there exist some good (and legitimate) applications.

Cryptocoins otoh... lots of gray area there. If not outright Ponzi schemes.

I hope some day, some crypto coin(s) will fulfill their original promise. But that day is not today.
