I think it's okay to make regular purchases every month, rather than just buying all at once with all your money,
The DCA method or all in method has its own advantages and disadvantages.
but the dca method can be said to be safer.
Actually, other methods besides DCA also have their own security, but sometimes they are more burdensome when someone wants to do it. Because methods like DCA are usually a little easier and not so burdensome when someone wants to do it every month even though basically they have to use capital when they want to buy it. However, the DCA method can always be tricked with our own abilities, which basically don't have to be in large quantities.
