Even if we would reach the mass adoption, what place would take Doge? I can understand that cryptos like ETH, EOS or NEO would be used for payments, other altcoins for other industries like real estate, travelling and so on, but in my opinion there is no place for Doge in the real world.
for now many people have used doge as an alternative to sending funds. and there are several online gambling sites using doge, this is one of the many cases of using doge. maybe not a mass adoption, but doge still has hope for it. doge cannot be compared to the Dapps project because they both have different goals. but try to compare with similar projects, you will see doge by being active and having users and fans every in the crypto community.
