at least if Bitcoin is legalized by the state, it allows all nations of the country to get an easy way to buy Bitcoin
that way, the existence of Bitcoin will become very popular and also the altcoin will follow a positive trend
at least with the regulation, we can have BTC safely and the prices are well controlled
I do not think that Bitcoin can come under regulation. Its idea was that no regulation is needed. In my point of view it gives people freedom.
