People would always have different insights some would prefer due to convenience where crypto is already being adopted but the negative side where its decentralization wont really already suited it out.
Being regulated would mean that there would be restrictions when it comes to implementing something but it would also be an advantage of the investors because the projects that would be launch would be properly checked before they would be able to collect some funds from the people. It would also be more trusted especially for those who are traditional who wouldn't believe something unless it has support from the government.
Its just really good as an alternative but some people do much prefer to be legalized but off of these things are actually contrary on cryptocurrencies true purpose.
If we think about it, having regulations really is opposite to what the creator of bitcoin is trying to achieved having a decentralized kind of currency that would be free from the control of the government. Form the looks of it, we still need regulation though but is due time, I believe we can do it on our own without the control of government.
