I personally have invested a little bit in ZCRT, they seem to be working hard and with real products..
ZCRT has only 1million emission and circulating supply of around 400k, the other ZCRTs are tied to ETH at 1:1 by smart contract.
I think I'll not loose money in this project and the benefits will be a lot..

Take a look at zcore.pay and zcore.network and see for yourself..
