DCA is for those who don't have much discretionary income available
I'm really short of words because it should be only newbie should think of this, that dollar cost average is for those that have not much discretionary income available, there is something that you have forgotten in Bitcoin investments and accumulating that there is many strategies in which many investors make use of, so it depends the particular one you think is suitable for you, than you saying that DCAing is for those that has lesser income available, why most investors engage in dollar cost averaging because this strategy or mothed gives every investors to invest at any given time without waiting for dip before buying.
Perhaps, Emjay24 is still a newbie and i was even thinking you will put your writing in a clearer context but instead you seems to be ''beating about the bush''. However, the DCA strategy is for all inasmuch as you have a discretionary income to invest, it does not matter whether you have little or huge amount of discretionary income. Perhaps, there will be times when you won't even have much discretionary income maybe because your expenditures might be higher which means you won't have enough money to invest but that doesn't stop you from investing with the little amount that is available at that time. The reason for the DCA strategy is for ease of investment consistently but you can still apply any other strategy you find convenient along with the DCA strategy so far as you don't go above your level of discretion.
