Knowing that investing in bitcoin is a long time investment, you should plan better and keep aside the money for investment as this will help you avoid anything that will alter your reasoning because as an investor you must be psychologically stable.
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.
You sound mixed up with your expression of HODL as regarding to the concept of the thread, the topic is based upon a presumption of Long term holding or investment plan of about 4 to 10years or longer which will create a better opportunity of experiencing compounding of your invested amount. This is what is being prioritize in the thread and not some buying and selling within the shortest possible time for profit maximization.
