Every privacy coin will be crushed by governments around the world because governments don't like privacy. They like control. It is a personal opinion about things. Grin is a privacy coin and governments will do everything to stop blockchains like this. I am not very optimistic about Grin even though I like the project a lot and they have received significant BTC donations before. I hope that I am wrong and that privacy is going to be built in as a must-have feature in crypto.
