If you took profit once, or it is not a regular thing, then it is okay to take profit. Do not just make it a regular thing because that is where it will affect the profit you are supposed to make from DCaing which should be the increase of your portfolio. Also if you are to make a withdrawal from what you have been DCAing, try so that it is not a very big amount that affects or takes out amount of money equal to what you will DCA for like three weeks. What I mean is, if you must withdraw, there should be a limit to what you plan to withdraw from what you are DCAing.
Sometimes taking the profits ones could be the beginning of your investment downfall because I have seen were someone who invested on Bitcoin and when he realized that his investment has gotten some profits so he now decided to sell off all the accumulated Bitcoin in other to have a good profits but with the intention of buying it immediately the price drops a little but actually little did he realize that he had made the greatest mistake on his investment because after selling his Bitcoin the price has increased so much that if he decided to buy the same amount he had bought before the number of Bitcoin he will get will not be the same even joining with the profits he had gotten he will not be able to get that amount, so he became disoriented that if he had known he would have not taking this decision and now a little profits he was chasing has cost him not only his investment but also with the chance of getting back to the investment because of the price increament of Bitcoin. So actually my point is that in as much as you feel that taking profits ones from your investment is good but however you should also think about impossibility of getting back to the Bitcoin accumulation after selling your investment.
That is quite a common problem of bitcoin in terms of guys who sell way too much too soon and then they become bitter.. and they keep waiting for dips that do not end up coming, even though they might have thought that they were smarter than everyone else by selling and making good profits.
