Indeed, for people who are optimistic about bitcoin, choosing a buy the dip and HOLD strategy is a good strategy to add to their portfolio. However, as an investment strategy, of course, buying the dip must be accompanied by controlling risk. One of them is by determining the target selling price when we buy when the price drops.
The topic of this thread is built upon a presumption of long term investing, and we are not trading here or even selling for short term profits and/or expectations to buy back lower.
if your investment plan is 4-10 years or longer, you are likely going to have better chances of experience compounding of your invested amount and also you will likely increase your options regarding what you might want to do with your bitcoin investment later down the road, especially if you both hold and invest more than one whole cycle... notice the thread topic also says nothing about selling, and that is on purpose (rather than an accident).
Bitcoin investment cycle should be aimed at long term investment because that os the only way to fully accumulate all the variables that usher in good profits, and yes indeed our focus in this topic is based on that fact, but most time, young upcoming investors who may not have the cashflow to hold they Bitcoin for that 4-10 year long term bitcoin investment cycle, because they are forced at some point to sell their Bitcoin to solve one problem or the other, or even applying the DCA approach so as to increase their capital with the thought that buying low and selling high based on short-term speculation could help the to achieve a more financially stable position, those set of Bitcoin investors will always speak based of their mindset and position, even though that, on the long run, the maximize profits in that practice cant match up with the one that comes along with just holding your Bitcoin for that space of time without doing any action either to sell with the intention to buy back at low which is what most call DCA approach.
