although the term HODLing tend to suggest that you have to hold it for a little while, investing in bitcoin isn't all that a long term investment as you suggest because the volatile nature of Bitcoin depict that you could have a reasonable returns even after a few month of investment unlike other asset like land that after buying, you have to wait for as long as five yeas upward before the value of the land will appreciate. We've seen the price of bitcoin rise to $42k this January and then dropped back to around $39k this same January so buying it now and after a week or two the price goes back to the $42k, if you sell it at that price, you've made your profit within the shortest possible time.
There's a great difference between a good investment and a great one, when you get your little gains in a short period of investing with bitcoin(I call it a gamble), you can say you had a good investment because you got gains at least, but having a great investment comes with investing for a longer period and that's the psychology and gospel behind bitcoin investment. Check the statistics and observe that those who really made a fortune from bitcoin investments are those that invested for a long term, they surely had a great investment.
I guess what you are trying to say is that investing earlier will give you a better advantage over those waiting for the price of bitcoin to drop to as low as $37k before investing as anytime from now, the market will experience a bull that will make people without a single holding to regret their inactions and indecisive nature. This is actually true because this is actually the beat time to invest because you are certain that you wouldn't experience any loss from buying at this current price.
I greatly fault those waiting for bitcoin to continue dipping. Why the wait?, you can get strategic with your accumulation so you don't lose out completely while you wait. You can go ahead with acquiring gradually with DCA while you wait for the dip you're expecting. If that dip comes by, you can buy with lump sum. If not, at least you're still acquiring bitcoin. Its a win win situation.
You're not certain of anything with bitcoin, you're only in anticipation, being certain is having absolute trust in something with zero possibility of failure. With bitcoin, we're only anticipating that the bull run once again will increase the value of bitcoin and bless investors with profits.
