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.
As far as I can see, continuing to hold is also a wise decision. Bitcoin halving is an advantage for the upcoming bull run, but what's even more special is that there are a lot of major tech financial funds already involved in holding Bitcoin. They certainly saw the potential future of Bitcoin so they bought and held it all at once. It is possible that this year or the Q1 of next year, the price of Bitcoin will break ATH $ 20k and grow to $ 30k. Meanwhile, those who hold $ 20k also have 50% profit.
