In 2017 when bullrun took over crypto space and many altcoins joined later some people still keep holding thinking that their altcoins will keep surging and surging, little did they know that bull season always have short life span when comparing to bear season, bear season can stay for years but bull season is just in months, so why are you holding when you should be selling?
Remember that some bought bitcoin at 20k and they have no choice but to hold till today, imagine all this year's waiting just to get back to where you once are. Bitcoin is over 18k now, good for them cos they are near recovery since 2017.
Know when to get in and know when to get out, don't be a greedy bastard.
the bullish season that is happening today is I think very different situation on what happen to 2017 bull run because of the fact that many big institutions, companies and corporations are now investing whole-heartedly to every cryptos in the market but still I have to agreed that we still need to be cautious and be attentive to the movement of cryptos knowing that the market volatility is very high so always keep in mind that take your profit even how big or small it is.
