Buying the dip is not for new investors but rather for old investors whom their bitcoin size is in a certain level, maybe 60% and above of their bitcoin target. They can wait to buy in the dip, so that their bitcoin portfolio can increase significantly when they buy more at a cheaper price. If you choose the wrong method as a beginner, you might end up wasting your time that you should have use to accumulate a good amount of bitcoin and you will miss the opportunities in the market.
Everyone is presented with the opportunity to buy bitcoin at a DIP price whether a new investor or an old investor so far as they have reserved funds. being new to bitcoin investment don't mean that they have a little amount to invest with because there are beginners that actually has a huge amount of money but decided to be investing part of it from time to time using the DCA strategy so will you also say that investors like that should not buy bitcoin when it DIPs simply because they are beginners?. A newbie buying bitcoin at a DIP don't mean that they would have to wait upon starting of their investment but they can still be investing and an opportunity to buy at a DIP price comes then they can buy with part of their reserved funds and still continue with their DCA amount.
