I think that regulation is something that is inevitable and more and more countries will decide to regulate Bitcoin in some way. But I don't think that regulation is equal to centralization. Bitcoin can be regulated and decentralized at the same time.
Regulation means seting some rules how Bitcoin should be treated, what is legal and what isn't, how it should be fitted into financial framework.
I think that regulation could strengthen Bitcoin and help it to be more accepted, we don't have to be afraid of that.
I totally disagree to that, regulation is not equals to decentralization but will finally lead it to centralization. The way most government view bitcoin is not the same we investors may view it. They may claim to regulate bitcoin but end up placing rules and law that will place bitcoin into the hands of the riches; there won't be normal circulation of bitcoin the way it is now.
I think you have somewhat misunderstood on previous statement. Here regulations means, a country specific framework. No countries will be able to control the bitcoin network. IT will remains de-centralized in all true senses. But the countries may provide regulations on how bitcoin or other crypto currencies should be treated within their country limit. They may legalize it, ban it or impose taxes on it. This is what is meant in the previous statement and that's true!
Regulation is inevitable and the way bitcoin is progressing, majority of the countries will legalize it in near future because that would provide them with a steady flow of tax income and also help the unemployment scenario to some extent. But no government will be able to control the bitcoin network in any way. They can simply tell their citizens about their entitlement within their jurisdiction limit.
