Because cryptocurrency sounds like a scam? Seriously, from the outside, a bunch of people with no standing whatsoever created a bunch of numbers on their graphics cards and call it currency. Now, compared to fiat currency, which in most cases is backed by a government with a long history, cryptocurrency sounds like a scam. There is a vast difference between a government saying something has value vs. a bunch of random people and an obscure Japanese guy (who may or may not even exist) saying something has value. Fiat currency has some measure of stability. If a gallon of milk costs around $4 today, it will probably cost around the same tomorrow. Can you say the same with cryptocurrencies? And which one?
