I didn't purchased them in the date you mentioned, but I had a similar situation in 2018. There were no regrets, but man, it was very painful to hold it in the red. Looking back now, I see it as a kind of "initiation" that everyone have to face at some point. Once it passes, you will collect the rewards in the next cycle.
The best way to hold is to not follow it. But it is hard when you are a beginner, you will be thinking about bitcoin everytime.
Bitcoin has experienced a drastic decline not only this year, but several times Bitcoin has experienced a deep decline. Indeed, what is most
memorable is the bearish trend incident in 2018, when a lot of people panicked because they bought Bitcoin before the dip. But right now
only newbies are panicking and selling Bitcoins at low prices, so indeed for experienced people, buying before the dip is not something to regret.
Because they know Bitcoin will surely recover soon, but in contrast to the newbie who will definitely have feelings of regret. Even though the thing
that will definitely happen is where we will buy before the dip, because the crypto market is very volatile and it is difficult to predict Bitcoin
price movements. So actually there is no problem buying before the dip and we don't need to regret it, as long as we can be patient and wait for
Bitcoin to recover again, then we can still make a profit.
