Actually many countries is regulating cryptocurrencies on their own point of view and even introducing their own coin, so i know vividly that since the existence of cryptocurrency and it's adoption is not all the countries across the world usually transact with bitcoin as exchange, so therefore i denote that not many of them like decentralized currency, they only look forward for anything centralized which is affecting some them of today, actually if an every country regulates and adopt the uses of cryptocurrency especially bitcoin, it will not have it's potential values again, so is better we further ahead with it like that.
From my perspective, some countries regulates crypto right now, but they are not full recommend or legalize it to the people, and with the same vein, restrictions are also implemented, so what is the need of regulations since the users is still living in fear because of government authority towards crypto. I think best option is to run your crypto stuff's in silent without anyone awareness.
Bitcoin has even become more complicated as the years go by because of the interruption of negative criticisms coming from the government. As long as they are just one sided, then the government will not be good for crypto as for now. They are making regulations for crypto and at the same time strict restrictions for crypto. So how do we expect people will react on it?
But since crypto aims for massive adoption, then it will not be fully legalized if its not being regulated in the first place. Regulations will make crypto more legal so that people will not hesitate to invest in it or use it as a currency knowing it is fully backed by the government. Because it is the government that control its citizens and if citizens will see to it that crypto is already approved by the government, eventually people will flock to crypto once they find it more interesting than fiat.
