beside news, i think if we understand about technical analysis,, we will know the right time to exit from the market in any situations
usually i use a tools such as fibonacci to predict the target price, for me its very useful tool
other traders use an indicators such as RSI to know if the price already hit overbought zone to know the right sell zone
and don't be greedy
I think the analysis doesn't really matter in a situation like this, who would have thought that some coins would go up more than 50% in one day.
it all depends on fomo or indeed market conditions are bull so all coins go up.
