No matter how much fluctuation there is in the entire cryptocurrency market, I am absolutely sure that cryptocurrencies will be the norm for "everyday" people in a not so far away future. Bitcoin might be the core currency, but only take a look at how rapidly blockchains are spreading now. Steemit, Manna, Onstellar, EOS, Bettex, Sancoy, the Abyss, only to name a few. I see all of them in the value of hundreds eventually ;)
