decentralization is one of the main advantages of cryptocurrency. there is no government which can stop bitcoin and cryptocurrencies, no matter how hard they try to do it
That is definitely right, governments cannot control BTC, it is the main advantage of cryptocurrency and no doubt people want to be part of this world cause of this reason. But l think the government would control it, that is why they don't want to see that people are depending. They always want people to depend on them. But it is impossible in crypto space, however, the government can make BTC legal or illegal in country.
You are absolutely right and it's what made Blockchain unique but how I wish as you said only having control on exchanges regarding regulation. If this regulation could come in crypto it will be very nice because many exchanges has exited scam and many investors had been hurt so would be good to regulate exchanges.
There are two faces of regulation and we can not tell which side will be beneficial for the crypto traders. The scam exchanges will do their job under a decentralization idea but without the regulation, it will be easier to keep competition among the top DEXs. China has lifted the crypto ban and Russia has followed this decision afterward.
