The reason why I believe this will be is due to technical reasons. The first reason is that if you look at the last major rally, and compare it to this one, they are about the same height now mirrored on a log scale. The second reason is that we are at a major at the 50% retrace of all time high to the lowest low after that high set. The Third reason is we have in the Overbought zone.
Since can be thin on weekends. I expect a major market player to try and move the price this weekend. Since a lot of people are trying to buy in on the rally due to FOMO, I imagine this market player will look to sell hard into the bid. This will push down the price, create fear, and the subsequent result will be a sharp sell off.
My target for the Sell Off is $500
