Bitcoin is an anonymous currency and I dont think theirs any law about supporting it in countries
Bitcoin can be used worldwide almost by anyone who knows to get around with it.
Why do you think that anonymousness of the bitcoin is also a roadblock for its path?
I dont see any way in how could something like that be harmful for the idea that the goverments will adopt bitcoin and other cryptocurrencies. If there are so many people using it, then why should it be made illegal?
Another important thing is that bitcoin gives a lot of different opportunities for normal people, plus it is a way to pay our bills, buy goods etc. without using banking system, just simple peer-to-peer payments.
Why do we need to use some bank services, If there is a possibility to speed up the things a lot? I dont see any point, unless the transactions will get confirmed in such a long time like we have right now.
