The people who predict an 80% correction are funny. You can't take something that happened in the past, and say "see, it'll happen again!". The public's awareness of cryptocurrency is 50 times higher than what it was back then. Corrections will not be as deep as they were in the past, simply because there are many waiting on the sidelines to buy in. And when they fail to get their target buy points, the price will move up to new highs on FOMO.
Hopefully you will be right. However, markets don't go up in a straight line, and chart patterns are fractal.
It's all probabilities, so take your positions and we will see !
