It seems very contradictory in the accumulation journey if we just started investing in bitcoin with DCA strategy and quickly switch to another strategy then such a decision will make you inconsistent throughout the long-term accumulation planning.
If we just started investing in bitcoin then we must be able to maintain initial strategy until the next 5 years and after that we can change the strategy that may be more aggressive or buy dips.
Indeed bitcoin investment requires lots of patience for you to be able to hold for a long period of time but, I disagree with your point which says you'll have to want for 5 years before you could switch strategies. Well individually we can accumulate as much bitcoin as our financial muscle could carry and that also implies that we could use the strategy that best suits us. The fact that DCA works really great for you doesn't mean someone else can use lump sum, buy the dip or combination of two or more strategies to accumulate bitcoin. What matters most is that you are accumulating at your own pace without stressing other needs. DCA is undoubtedly one of the greatest strategies i have come across but that doesn't mean it will work for everyone thesame way. Some persons due to realization of missed opportunities in the market after they have been educated about bitcoin they might initally start with DCA strategy but when they have done some deeper research and have become more enthusiasts about bitcoin they may decide to put in all their fiat savings at once by using lump sum and continue with DCA from their monthly wage.
