Bingo. There's not really much overhead to creating a new cryptocurrency, so worries about deflationary pressures should be removed since new currencies can emerge. The currencies will emerge out of specific cultures, in this case the meme culture, but as we've seen in the past, through various gaming cultures and as someone else suggested "Bieber-coin". (Exercise for the reader: is this much different than dot-com bubble paper millionaires with thousands of options?)
Think of who is in the 1% of a country's wealth--a mix of capitalists who were good at acquiring that currency and folks who inherited it. In the cryptocurrency world, the moneyed are the creators, the miners and in the case of dogecoin, the creative-meme class who serve as a marketing arm. Many of them are in it for the lulz, and consequently have great upside with little downside, since it will always retain an intrinsic value as a karma proxy. The speculators may inadvertently make real-world millionaires out of this class.
It would not surprise me at all in the next year to see companies with large social subcultures at least attempt to launch their own cryptocurrencies, or extend their in-game currencies to become linked to a cryptocurrency.
