What I personally think is, if true, many countries start implementing regulations for crypto currency, will this change the nature of crypto, namely decentralization to not being fully decentralized?
The regulation of cryptocurrencies will be possible without affecting the basic natures of cryptocurrencies. Yeah, I am sure there will be possible regulations in a way without affecting the decentralized nature of cryptocurrencies. We cannot expect the same way how government is regulating corporate and other organisation but they must need to take different stand against the cryptocurrencies so that it will serve its real purposes to the people.
There will be no point of regulating cryptocurrencies by removing its all basic characteristics instead of doing like that then government can go for their own digital currency because after removing out all the basic characteristics of cryptocurrencies it will remain like fiats but in digital form.
