The reason why I'm optimistic about Mixin Network is its use of use and diversities. People no necessary to pay more attention in how to use Mixin Messenger to keep their assets safe while are clear about the transactions he performed. It's really to send tokens to the ones you know, just like send messages using any instant social messengers. Actually, besides the tokens listed on Mixin Messenger, I guess all kinds of token are possible to be stored, transferred, paid in Mixin Messenger just like the idea Mixin Network stated: All cryptocurrencies accepted in Mixin Messengers. I like that.
Guess we should be more confident about the future of cryptocurrencies, Mixin Network as well. It is for sure that the blockchain & cryptocurrencies won't disappear, won't die, just in the tough time facing one of its biggest challenges. We will definitely have a new-round of bull run, and when it comes, what didn't kill you will make you stronger.
