In hindsight, I can see that Bitcoin's only chance for a bullish bounce was from the long daily wick on 6th Feb, but it should've started providing higher highs, i.e. not double top just shy of 12k.
From that moment on it was clear for an experienced trader that we're in for at least months of bear action. I still believed for another couple of months that we'll resume the bull trend, but hey! that's how you get experience, right? :D
It has been and will continue being a painful year, but I believe these are lessons that will yield profit for you as a trader over years to come, applicable in any market.
