As a new investor I can say that if you want to hold bitcoins, you should hold bitcoin in DCA method.
As a new investor I don't think it requires much knowledge.
(Though the saying goes that knowledge is king)
But once you go to the market, you can learn all kinds of things by yourself.
Because of how big the crypto market is, and the way it is built, you need the basic knowledge of it to succeed because nobody learns everything by themselves as a newbie without the directions of others. And not every new investor in crypto knows that if they hodl bitcoin for long, they will be at profits, by using a DCA method. Therefore, some new investors had sold their bitcoin holdings out of fear because the bitcoin they tend to hodl for a long, decline in price. Making them to be at a loss price without even knowing there is a chance for them to be a profit back, just a matter of time.
