As far as I know, buying dips is not for an investor but for a trader.
I don't know where you learnt that from, it's certainly not from this thread. From what I have learnt from this thread, it is said that buying the dip as a method of bitcoin investment can be used by both traders and investors. The only difference is that investors shouldn't wait for the dip as traders do. Investors should continue with their dca and when the dip comes along the line, they should capitalise on it and front load their portfolio if they have more discretionary income available. So I don't know who told you that investors don't buy the dips. It's important you pay attention to details when you find yourself in a learning environment as this, before you fail exam and fail correction.
DCA seems to me to be the only investment method.
DCA is not the only investment method, but it is the most widely used method. It is the recommended method for newbies like us.
So I think the only way to invest is DCA.
Even though we are encouraged to use dca method to invest especially since we are new to bitcoin investment, I think it is imperative we recognise that other methods of investing are in existence. So that should we be called upon to lecture and educate others outside this forum, we won't be giving them half baked information. That being said DCA is not the only method to invest in bitcoin. Please take note and take correction.
