Except it's conceivable that having virality baked into it (e.g. being a "joke/meme") could actually help its adoption move much faster than it otherwise would. And once you have a cryptocurrency that has a lot of buy-in, why not use it for real transactions?

I'm not ready to say DOGE will win the cryptocurrency wars, but it certainly wouldn't the first time that a "joke" or "hack" turned into something real and lasting.
