Most folks who are merely investing DCA from their income, they might ONLY be able to invest 10% or less of their income, so if a person invests 10% of his income, it would take around 10 years for him to have had put a whole year of his salary into bitcoin.. and so frequently we have the investment being a product of both time and how much we put into it, so some guys get excited to cash out their profits, but if they have not put very much into bitcoin, then their profits would be less likely to be meaningful. We have all kinds of examples through bitcoin's history where guys had been cashing out way too many bitcoin too soon because they got interested in short term profits, but then they ended up selling way too many bitcoin too soon and ultimately were not really managing their bitcoin holdings in a way that would really bring meaning to their fnances and their overall net worth.
If a person's monthly income is $500, then 10% of it is $50. So 50×12=$600 in a year, then in 10 years, 600×10=$6000. And two or three bonuses a year can be added to the fifty percent. I said fifty percent because the remaining fifty percent will be needed for the family. Sometimes when the market goes down in a big way, it is better to keep some money to buy Bitcoin at that time.
