I sold at around $6700 and I lost money. But I still cannot understand where I made a mistake. The market was bearish and it doesn't make sense to me to hold when the price is falling every day. What if bear marked lasted 2 years? Most analysts that I was watching on youtube predicted further decline at that moment and I wanted to minimize the loss. Everyone was sure that it was going even more down. There was a huge number of shorts!
But for some reasons it went up.  Someone pumped a lot of money once and after this initial pump the price started growing every day. How could you possibly predict something like this? This situation doesn't look logical to me.
