The value of any currency is determined primarily by the confidence level of those using the currency. As long as there is confidence that the currency can be used to purchase goods and services, there is value to the currency. This is very good news when it comes to STEEM and SBD as far as I'm concerned, because the larger the Steemit user base grows, the more confidence (and value) we'll see for SBD and STEEM. Just as we keep hearing that this is just the beginning for bitcoin, the same can be said for Steemit, which means there is probably unimaginable upside potential.
