hmm... cryptocurrency is a digital money online.
so how can be having money online will be a crime?
does it mean that having money in my paypal,webmoney,skrill etc.
is also a crime? its non sense.
well if using bitcoin really become a crime.
it will be a disaster because a lot of people will argue about it.
this will be a world wide rally..
It is a crime if a government wants it to be a crime. In the past, you can read about that, governments often forbid alternate currencies when they felt they threaten them. They want to rule about the money. They surely don't want to give that right away. So they forbid alternate currencies pretty often.
Paypal might not be a problem because it still is pegged to fiat currencies. And the governments control those.
