Bitcoin is new technology, the fact that its use cases are changing is evidence of that. That should be exciting, not disheartening. It would be a worse sign if it simply accomplished the goal it purportedly was intended for and nothing else. This shows it may have more growth potential.

I for one know a few folks who have used bitcoin to transfer large sums of money across borders... pretty crazy times we live in. I expect bitcoin to dominate in this area in the short to medium term.
