MimbleWimble-- once people realize what it can do-- will make people give Litecoin a second look. I only found about about it thanks to research I did for @crypto-guides. Privacy is even more important now than before, and we need all the tools we can get.
It will also make people realize that if an old coin like Litecoin can get new functionality added, then other pre-Ethereum altcoins can be upgraded and perhaps gain a 2nd life.
