Cryptocurrency is being decentralized so if we want it to be regulated by the government well it would be lose it's uniqueness.We do not need to regulate cryptocurrencies but regulations can be also helpful with the adoption and growth of them or they can be restrictive and even prevent the adoption altogether.In the end it will come down to what they are regulating and how.If it is regulation of exchanges and if it leads to a more secure place where people can trade with less risk that would be a very good thing.
