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.
What of a situation whereby a newbie enters his investment journey during a dip and has some big discretionary income available at his disposal. Are you saying he shouldn't take advantage of the dip and acquire as much as he can because he's a newbie or should he wait until after the dip tho start his accumulation journey. Of course not, he would buy as much as he can and follow up his investment with regular DCA accumulation. So the dip is for everybody, both new and old investors alike, but waiting explicitly for the dip to start your investment journey is a bad investment strategy. The dip is an advantage to buy at lower prizes and not to be totally dependent on to invest in Bitcoin.
According to the statement I made bold, to me the key thing here is regardless of a newbie or not, it's best he invest only what he can do away without, because if he buys more than what he can do away without, at a point he will still falls back to his investment, due to the fact that he use everything to buy aggressively, which is doing the right thing the wrong way.
So the money that would funds his daily, weekly or monthly needs should never be tempered with no matter what, because it's very much important to invest only what you can do away without irrespective of how dip the price of Bitcoin goes.
Though it's a logical approach to buy aggressively during a dip, but it's very much important that you buy only with what you can do away without, so that you wouldn't temper with it in the nearest future, so in essence of what am trying to say is that in all you do as a Bitcoin investor, try not to invest all you had, including your emergency funds, so that you can have something to fall back to during the rainy days.
