This is the true reason why DCAing is the way to gain profit.

Before I explain why DCAing (Dollar-cost averaging) is the way to gain profits in the cryptomarket, let me tell you one very important fact:

We all can agree that nobody knows when we are at bottom, a high, a peak, a ATH, bear or bull market unless we are in the future and can look back at the past.

As example we can look at the BTC or ETH lifetime chart and zoom out completely. We see something like an outline of a mountain formation with peaks and sideway lines. Peaks only last several weeks while sideway region can last years!

This is the keyword: years(!). When you DCA, you spend weekly or monthly an affordable amount of fiat and invest it in cryptos. The chances are pretty good that you doesn't invest too much at peak or high times because they just last few weeks, but instead most your total sum of invested money from DCAing gets invested while the price it at the sideway region.

Also it doesn't matter if you strictly continue to DCA despite feeling/being in an obvious peak or decide to stop DCAing while peaks occur, the time and amount of money spend at peak are so low compared to the money spend on sideway/bear times.

Disclaimer: I am no financial advisor, nor am I some expect; just saying what I had thought while under the shower and wanted to share and discuss it with the community here. There are coin that can "moon", there are coins which future will go towards zero...nobody knows it except someone who owns a DeLorean with built in Flux capacitor. Nevertheless I wish us all a golden future some day.
