The price of Bitcoin makes a lot of double bottoms. Usually if the more recent bottom is lower, the price goes down. I'm hoping that the current short-wavelength pattern is a triple bottom. (3/15 then 3/18 then now). If this bottom is higher than 3/18, the price should go up. The 3/21 peak wasn't high enough to overtake the 3/12 peak so we need this extra bottom for the price to go up (prices above $8600 give me hope).
I always referred to the triangle patterns as "guitar strings". The price will go way up, then way down, then half-way up, then half-way down, "vibrate" and then settle. Usually Bitcoin breaks out towards the end of the "settling". When the stock market index does a "guitar string", it usually signals low volume and the market goes lower at the end.
I'm concerned about the volume right now. During the most recent rally, low volume meant the price of Bitcoin went up. During the crash, low volume meant the price of Bitcoin was going down. Now (low volume), I think people are waiting to see what will happen.
