I think KYC is needed in some point, because of the legal state of crypto. This might prevent the widespread opinion, that crypto is used only by criminals. This is also a message to me from the trailer of new movie with Kurt Russel - Crypto...its just for criminals....sad to see it.
But in the future, meaning 10-20 years forward, the crypto will be less trackable, implementing better and better ways to do it even to Bitcoin and Litecoin (for example Mimmblewimble).
