It will help to protect the citizens,
But it doesn't mean that every user is 100% safe from hacking/scams. Also, if regulation will come, the real purpose of crypto which is decentralization, will be put to waste. Though, regulation may help to increase or to boost the usage of crypto in each and every country around the world. However, as I have said, regulation will bypass the decentralization which is one factor why we are using it.
Indeed, if a government put a regulation on using crypto then I might say that it is good but also "a little bad" at the same time. It is good in a sense that such act helps us to get more secured, you are right. However, for me it is no longer called decentralized since there is already in control. Our move is not monitored which kind of intimidating for me

(you're right on that context as well). But the question is, which weighs heavier? If I will be asked, getting regulation is
not a must because I think it will be the same. Having a regulation doesn't mean that we will now be 100% free from fraudsters, so what's the big difference of it from not having one?
