If you mean a decentralized blockchain environment that is immutable, yes, why not?
Isn't that the sole vision behind cryptocurrencies? But I don't think it would be as easy as it sounds to achieve. The control game is addictive and the governments will never let that go.
Also, the vulnerability and scams keep ruining the market's image and raise questions regarding investor rights and safety.
There is a need for a robust system that is decentralized and gives its users the freedom and security both. There are constant efforts in this regard, the good news is industry is starting to accept crypto and will definitely shift the focus on these issues. Recently, I have reading about a new project Virie, that claims to be decentralized and distributed exchange. The need is to build such tokens and spread as much awareness as we can.
