Welcome to the world of cryptos....it is volatile, there is no doubt about that.
However, price action is no reflection on the value of the blockchain. What has changed since yesterday or the day before? The developers are still going along the same as usual. People are still on here posting, commenting, and upvoting. Steemit and Dtube are still moving up the Alexa rankings.
All is well...price action is not indicative of what is really taking place.
