Indeed I don't. Nor do most other people. That's one of the reasons why, to first approximation, zero people are using them. And even if lots more people suddenly begin needing to transfer non-reserve currencies internationally, these transfers are going to run into legal issues which, despite fantasies of bitcoin enthusiasts, are not going to be evaded just by putting "crypto" in a prefix.

Your claims are fallacious. Most people, i.e. 51%+ don't use USD or EUR. Many people also make international transfers. There is a use-case and your observations that zero people use btc are anecdotal at best.

Pray tell what kind of legal issues would suddenly arise if it became mainstream.
