The reason why I tell newbies to be careful when they're thinking about deploying most of their capital in this kind of market is the possibility that they might not be mentally ready to go through the volatility.
Newbies often get scared because of FUD and FOMO.
It's about knowing why dips are okay and why it's not okay to drop your begs during them.. Once it clicks, it becomes like a charm

A new investor should not focus or looking on how to time the dip before they buy, rather get should focus more on using DCA method to increase his bitcoin portfolio bit by bit. DCA gives you the opportunity to buy bitcoin weekly regularly irrespective of the price of bitcoin. Yea of course, it's good to buy bitcoin at the dip if you're prepared for it with your reserve funds. However, a a no coiner or low coiner looking for how to buy bitcoin cheap will be a big hindrance to increase you bitcoin portfolio faster.
This is because nobody knows when the dip will come and you might end up with no direction and target which might end up in a fruitless way, because when the dip comes, you might not be ready since you're not a magician to know when the dip will come. You might also say that the price hasn't reached the price you want. All these are excuses to cover up for your unseriousness towards investing in bitcoin regularly because you love cheap things. It's good that you focus more on quantity to accumulate rather than what price to accumulate so that you don't limit your chances of improving your financial strength in future when you're old.
