I don't know if anyone else has different opinion about it?
DCA will helps you to your average price. Technically, it really help people to acquire more Bitcoin if we will compare on buying at higher price but having an extra income is the best way to acquire more Bitcoin since you will not get more Bitcoin without putting more money on it as your investment. DCA just average your buy price but it doesn’t increase your Bitcoin amount since you are just buying using your fiat.
Get a decent job that pay more. This will helps a lot to acquire more Bitcoin then apply DCA to have an average entry price to have a optimum profit once bullrun occur. DCA is not a game changer but rather your decision to continuously buy Bitcoin using your fiat.
