Any strategy that you decide to adopt for your Bitcoin investment is your choice inasmuch as you are increasing your stash. If I'm a millionaire or billionaire, I probably won't have the time for weekly or monthly DCA method, I'd likely be buying in lump sum, maybe once or twice in a year. The important thing is that I'm not relenting in stashing my bag, besides, the amount that a very rich person can use to accumulate once will be far greater than the amounts of many low income earners who are diligent in their weekly and monthly DCA. For those of us that doesn't have the funds to buy in lump sums we are the ones that needs monthly and weekly DCA method the most, because we don't have excess money to buy at our own conveniences.
If you're not very rich and you don't adopt the DCA strategy it'll be very difficult to actualize the long term hodl goal. If you don't use the allocation from your limited income to buy Bitcoin something else will collect it. If you have a long term Bitcoin accumulation plan using DCA method, you should not worry about current price as at when you're buying. That is why it's important to have basic Bitcoin knowledge before going into it so you'd understand that at whatever price you buy, Bitcoin has the potentials to increase and always reach new ATH.
Totally in support of your comment on this. There is no discriminations in strategy when it comes to Bitcoin investment. Its like a farmer going to the farm with the right tool that makes work easier and faster for him. Every investor must find a suitable strategy for himself. That is one of the most important step to take after deciding to start an investment. The choice of strategy must in turn align with their financial strength, investment goals, risk tolerance and so on.
I wont deliberate much on this, I believe we are wise enough to know what we want. We wear the shoe we know where it pinches us. If we invest using a strategy we cannot keep on with, there is no way out of the mess we may get into.
