I think one of the big reasons cryptocurrencies have had such slow growth in comparison with other Technologies is that so few people understand what it is. Much of the value found in any currency is the trust placed in its value by Society. That is where a social media platform such as Steemit becomes so vitally important for the future of cryptocurrencies. It takes the abstract ideas of a digital currency and puts it into terms the public already understands in a social media platform and an estimated value in traditional currency.
