As soon as doge is the most profitable coin, it will be mined by ASIC farms and multipools and then dumped on the exchanges making it not profitable again. So I think it's about time for the DEV's to really think about capping the coin as it was introduced in the first place, maybe change the PoW algo, and hey, why not also implement PoS? Of course that would need a hard fork, but it's possible without problems.
Do not let such a great thing as doge just slowly die...
Actually doge was never capped , it was a mistake done by the dev which he realized only after a month and decided not to patch it but to go on with it , since it was a joke coin anyhow.
And there is no hardfork without problems , especially when the coin is that distributed and daily used like doge.
