Nothing new in DGB = no reasons to grow, old coin = no prospects. It's better to look for new coins - they still have growth ahead, for example: Phantasma, NKN, Pchain, FuzeX, MAN.
Bitcoin should not grow then, it is 4 years old coin and you say there is nothing new, it basically does not need smart contracts or AI like bitcoin. If you are right then most coins including bitcoin should die in the future.
