I am intrigued upon the first two: panic selling and postponing from trading.
On doing panic selling, ones tend to sell their assets in the price lower than in the actual price. The main goal is to sell their coins faster to save themselves from the worse situation, without consideration upon the impact of their behaviour towards the market in general.
Meanwhile, ones could also hold their assests and postpone from doing any trading activities, in order to keep their assets safe and even maybe went on hiatus from digital assets bussiness while waiting for the bullish days to be back. They don't want to sell their assets in low price, but the act of not doing any trading is logically also has impact in general. At least, it is contributing on slower the trading traffic.
In your opinion, which one is the worse way among the two?
I would argue that panic selling is the worse option. It not only impacts the market, it also impacts the trader. I just think about the people who sold their Bitcoin during early bear markets, and how much they must be kicking themselves now.
