Waiting for a drop to buy Bitcoin prevents investors from making more profits. What we can learn from the past Bitcoin equation is that its price will be higher than expected. High profits and investment go hand in hand, so you should invest in Bitcoin from today, with a time horizon of ten years rather than five years. Sometimes it is better to focus on holding Bitcoin than to make a profit. In the hope of making more profits in the future.

Well it is true that there tends to be a bit of evidence that a person is prioritizing his bitcoin investment if he regularly invests whenever he gets the money, such as on a weekly basis, and so there could be a bit of lessening of the priority if the guy believes that he is going to hold that extra money on the side and wait for a dip (a dip that may or may not come). 

Sure there are ways to split up the amount of money that a person has available and to invest right away with some of the value and to hold the other part of the value for buying on dips that may or may not end up happening... yet , surely a presumption of having a limited budget is that it may well not be very practical for the person to be holding back value, since splitting it up does not really rise to a very high level.. or at least not necessarily a high enough level to justify splitting the amount into two parts.  So part of the advantage of mixing strategies is that any person can sometimes find himself in a situation in which he usually does ONLY DCA, but some temporary circumstances might justify that he mixes up the strategies and perhaps throws some funds into the buying on dip category or just lump summing based on the quantity of funds being available help to justify that buying right away and with a lump sum might be a good way of deploying such funds (or a part of such funds)..
