Always make sure to have a bunch of fiat ready to put in action would the price tank hard. One last high volume flash crash wick could signal an actual bottom that people on a large scale would agree on that it is a bottom. People focus on double bottoms, v bottoms, etc. It could speed up recovery if so. Currently people are still in doubt due to how ugly the charts look.
For good reason too. Even if we do another leg up to $5K+ it could easily be a bull trap like late 2014. Without a clear reversal sign (like the high volume V-bottom in January 2015) it's only sensible to assume the bear trend will continue a good % of the time. That's why we call them trends.
