the biggest thing that makes them go leave is that they got lack of knowledge about crypto and the market, they're being moved by their own ignorance about this, and let them be, it is not your lost, but it's their lost.
ignorance will have an impact on the desire to explore crypto that keeps moving. Out of 100 traders I am sure half will return, this is because they are reactive to every crypto update and even more on the market when facing situations such as these few days that are experiencing a good trend.
Leaving the market just dominated by people who are weak in intention they are for crypto.
