I think having privacy platforms is going to be super beneficial to the world of crypto and how we transact. I keep seeing the project Elixxir pop up which is a digital currency platform with a built in messaging dapp. Like a miuch better whatsapp or venmo if you will. I think it will be the type of project that will catch mass adoption
In my opinion, I think privacy coins are the way forward, you wouldn't find it funny if your bank account balance and all your bank transactions are made public, but this is exactly what blockchain does and it is turning people's wallets into targets for hackers.
