Earlier quoted context omitted.
Normally if you stole euros you wouldn't need to first sell them for dollars to get value out of them. Cryptocurrencies are not currencies, not any more than rare postage stamps are.
> Normally if you stole euros you wouldn't need to first sell them for dollars to get value out of them. I can't pay with dollars in most of the shops in Poland.

They literally sell and buy different kinds of money.
