I agree with everything you say. Probably a lot of people cashing out, taking some profits, FOMO, and I think a correction in the entire "altcoin market" is coming. Remember the entire altcoin market seemed to pump at the same time. Almost every chart I look at appears to be over bought and pumped. Many coins seen incredible gains of 100 % - 300% and more. Many of these same coins are starting to correct now and the price will adjust to the market STEEM and SDB too.
