I am very positive about DMME. To me it is holding up great, has received lot of attention for crypto community and the project itself is very promising because I personally would like to have a completely decentralized and anonymous messaging platform which no current so called messengers provide.
Everyone is free to do their own research but I am running a node and also staking to gather more coins and I am on it for long term for sure. Another point I forgot to mention that it has low emission and supply which is why price will be holding up pretty nicely, unlike other over inflated masternodes/PoS coins.
