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.
It seems you don't really understand much about the concept of holding because you would not have said that holding tend to do with short time investment however when we talk about holding we are actually referring to long time investment by buying Bitcoin and holding it for long, and secondly no matter how volatile Bitcoin may be but is never a guarantee that you could have a reasonable returns from your investment during the short time you are referring to, although is obvious that profits is always the major goal of every investors at the end but with lack of investment planning could make someone losing instead of making profits at the end. So perhaps if your strategy is dependent on the volatility to make profits within a short time I would advise you to re strategize and focus on holding instead.
