When Dogecoin was introduced it was humiliated by many. People referred it to be poors' cryptocurrency. But as time passing and BTC fees and confirmation time going out of everyone's reach, Dogecoin has gained repo. Even I personally love sending doges, as fees is hardly between 1-2 units and transaction get confirmed within minutes. So if BTC and other major cryptocurrencies keep facing scaling issue, believe me Dogecoin could worth 10x more in three years.
