I am not fan of anonymous cryptocurrencies. Why? Because simply they can be replaced by second layer solution - for example Lightning Network increases the anonymity of Bitcoin. Secondly, governments will 100% ban pure anonymous coins.
The governments will never approve anything to take over itself from being in control. But the blockchain technology is so revolutionary that the governments will have to approve it to be in co-existence with itself that is why the governments will have no other option to regulate the technology and use it.
So we kinda know what's eventually gonna happen. Better to stock up some potential coins
I will not side with anyone, government or bitcoin but many possibilities in future can happen in my perspective. It could be that bitcoin would be completely banned and it could be that bitcoin would continue to grow side by side with fiat, this depends on how we make changes now. But I really hope that bitcoin will continue to grow even though possibility is still fifty-fifty.
I believe cryptocurrency will be bright in the future and not just for privacy coins, but if people have to choose privacy, then we will see the new trend will be on the privacy coins. That will make privacy coins will increase in demand because many people will want to buy that coin. But the government cannot control cryptocurrency as they can't stop the cryptocurrency unless they cut off the internet connection, which will impact too many things in our life.
Indeed, any government cannot stop control of crypto. But they were able to freeze all crypto companies like exchanges that were able to knock out all coins. Except they all transact on the darknet.
