My thoughts about DOGE:
Doge is a community-driven coin with copied features of LTC.
The success of DOGE stand or falls with the feedback of its community.
It's not like LTC innovated much over BTC did it?
I think DOGE can be big in the future, when cryptos are very mainstream, like a crypto for kids sort of things, to tip people around, people is eager to tip with BTC for some reason. DOGE community is also huge and do a lot of charity type projects.
