I see a large amount of sell orders for DogeCoin, and from the looks of the Bear charts, DogeCoin looks like a dying currency. If I was looking for a "long-term" currency, DogeCoin is the one I would avoid...?

Interested to hear the community's thoughts on this?
Yes, apparently there is no future of dogecoin. The developer himself left this so there is no hope for this coin. Better not to invest. if you really wish you can invest just $10 and buy few thousands of dogecoin and just forget about them. $10 might be $100 in 10 years of time etc.
