Now, there are two scenarios:
1. Users prefer bitcoins solely because it is decentralized and pseydo-anonymous. They do not want it to be regulated by a governing authority.
2. Users who think that even if bitcoins get regulated, it would not matter much. They are okay with accepting the centralized, tax paying, non-anonymous version of bitcoins.
First of all, even if bitcoin is not legalized in a particular country, users do have to pay taxes on conversion. Secondly, it is not entirely possible to enforce a complete ban on bitcoins so if bitcoin is even banned, users can still somhow escape without any legal implications.
But after Japan legalized bitcoins we have seen a tremendous spike in bitcoin price. Solely because when a governing authority backs and legalises bitcoin, not only it gets huge attention, but the citizens of that country believe it is something legal, it is something new, it is something technologically advanced, it is something that has future, it is something that we should try.
So the point is, IMO the more countries legslise bitcoin, the more it would grow, the more the bitcoin community and users would benefit from it. Obviously on the downside decentralization would be taken away, I guess at least partially.
So what's your opinion, do not want bitcoins to be regulated and let it grow on it's own or regulation is required for global adoption of bitcoins.
PS: I mean by global adoption, not 10% of a country's population using bitcoins, but at least 50%.
legalization of bitcoin is very good. Gives good publicity, better trust, etc. But regulation is something else. One of the main pros of bitcoin is its decentralization; this almost defeats the purpose.
In my opinion bitcoin in the future will be good on its own even without legalization/regulation.
But yes, your point is true. more legalization, more growth, more users.
