I think everyone should use bitcoin, regardless of political boundaries. It's what ties everyone together, from me to some shithead scammer living in a dirt floor whorehouse in Africa. This is what I like. Governments should stay the fuck out.
I agree. It's better to have one currency like bitcoin instead of many separate currencies as it's much easier to transfer to someone in another country(not having to exchange currencies). I also agree that governments should not be involved as they could potentially have some control over their cryptocurrency.
