Part of the problem is that bitcoin was such a one sided market for so long people sort of presumed up, up, and away. So when a decent correction came panic struck snowballing the selling. Many big players entered the market last fall/winter during the height of the inrush of capital. Big money in means big money out during corrections and much more volatility. Great if you can ride the surf but not so much when the wave crushes you. Cryptos gaining popularity is a double edged sword sometimes.
