Some people just initiate the habit of procrastinatiion and tag it that they are waiting for the dip not knowing that they are indirectly doing their bad, this habit is always common with newbies, I don't even know the reason why a newbie will want to wait for the dip, someone that has no fraction of Bitcoin at all in his or her portfolio that's is supposed to come up with a strategy to start accumulating Bitcoin gradually, Bitcoin investment is very much easy if any of this guy's understand how to go another it, yes you are right what you said, if someone can keep DCAing and may be decide to have some amount of money to invest heavily during the so called dip then it not bad but as for relaxing comfortably waiting for what they called dip before they can invest, I think that idea should be relegated totally because it wouldn't do anyone any good.
Many individuals, especially newbies, usually say they are waiting for a dip, but in my opinion, they are just using it as an excuse not to start. The fact is that no one can predict the right moment for the dip, and waiting for it without investing is just a waste of time. Instead of relaxing and waiting, we should start with whatever we can afford and be consistent in our accumulation, even if it's just buying gradually with DCA.
And those who have yet to own a Bitcoin should not sit back and wait for the perfect time, instead, now is the best time to learn gradually and get confidence over time. Waiting for the dip makes people miss their chances because they become tired of waiting. Of course, waiting for a dip before making a move should not be advised to any newbie. Start now, keep going, and improve from there.
