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.

DCA is a good strategy for holding Bitcoin.DCA means buying and holding a fixed amount of bitcoins every week or every month. You invest 1/3 of your income over a period of time. You cannot hold on to your entire income or invest too much at once. At any one of your perils you feel like withdrawing this full amount.Which will go against your dream of holding bitcoin.
