Only pool i know is : http://coinsforall.io/#!/coin/DTC and it work pretty good, maybe contact them to know how to run a pool and make a donation % mining pool that way it can fund to be listed on other exchange, discord group is a better place to talk over this old forum way. Just giving idea but i can understand you are busy and just let die this projet.

I dont know, website not really updated, only know of 2 exchanges, no update on twitter, outdated exchange on delta and blockfolio.
Thing you could do ( my idea) because i believe this is a good projet.

-Add people on the projet if you are doing this alone or you just took over a dead projet
-Create a bigger storage capability on the chain to be a "icloud decentralized"
-Make a official pool and make a donation pool to fund the projet for recruting people, make it on other exchange.
-Create at least a Discord group.

Where is the team of this coin ? Why let it die ? Beside freiexchange and btcpop is there on any other exchange ?

Your best bet with cpu mining would be Zoin coin since its only Cpu mining coin that is the most profitable right now, otherwise try nicehash. Unless you dont pay electricity i dont recommend doing so.

I know its a old coin, but cant find any clear information about solo mining, ive downloaded verilum version and when i type setgenerate true it crash or when it work when i try to connect at my locall adress it look fine but it stall at bitcoin signal 127.0.0.1...
