Bitcoin is a volatile asset and so there's no guarantee that you will get 2x or above that amount from your investment at the end of the year. Realistically, thier might be years when we are not all that profitable with our investment and Bitcoin might remain at a certain range of price for a long time during some years before we tend to see anything close to 2×, 3× or so as you may have it.
That's basically the whole essence of long term investment and the application of the DCA methord in doing so because while you're investing for the long term, even when you don't see yourself in a good profit at certain time, you just take it as an opportunity of buying more Bitcoin and to continue doing your DCA till you reach your accumilation goal.
I agree with you that using the DCA method to accumulate Bitcoin does not guarantee that we will be getting two times our investment at the end of the year because Bitcoin prices can stay stable for several months. The DCA method is easy to understand, but it is dependent on the amount of money and how the individual wishes to invest. However, some individuals who invest using DCA methods, invest once a week, whereas some buy once a month, however, it's necessary to understand that the DCA method is always profitable for long-term investors.
Furthermore, using the DCA method requires an ongoing strategy where buyers are not bothered by the changing price of Bitcoin and continue to accumulate for a long time because the specific purpose of using the DCA method is that you can buy at a high price and buy at a low price for a long time until the investors become successful with their investment.
You are absolutely correct, some people think that since DCA is the best and reliable strategy that success is sure or certain not knowing that they are the one that will make the strategy work. Someone's success in Bitcoin investment whether using the DCA, lump sum, buy Dip depends on the investor's consistency, discipline and the ability to manage investment and I want to let us know that every individual has an atom of management skill in them but is just left for them to build or grow it.
you know, doing DCA comes with being consistent with your Bitcoin accumilation. As a matter of fact, what makes DCA an effective approach or the most effective approach of accumilating Bitcoin is that it encourages being consistent with your accumilation plan even though you're not using a very big amount per buy.
The goal might be to accumulate a certain amount of Bitcoin say $50k worth of Bitcoin for an interval of 8 years which might be your comfortable zone depending on your financial capacity and then you can break it down into series of step by step accumilation plan so that you can reach that goal at the set out time while putting into consideration that Bitcoin can still go up while you're yet at the accumilation stage. You've got to consider variables like the need for striving to be consistent with your investment schedule while also extablishing the fact that there might be times you might miss out on an accumilation schedule which will slow you down from reaching your goal faster enough. But regardless of this, consistency with ones DCA is the fastest way of reaching your goal in your Bitcoin investment.
Investing $50k into bitcoin over 8 years should totally be within reach of some one who currently might be able to invest around $71 per week with perhaps some anticipation that over the coming 8 years his disposable income will increase and he would be able to invest 10% more into bitcoin each year. It would look something like this.
Of course over an 8 year period of time, a person could have a regular DCA amount, but also there might be times in which cashflow is better and/or times when cashflow is worse.
We also cannot really be sure how many bitcoin that might be accumulated through such a strategy, and perhaps we could attempt to project that out too by adding columns in regards to the anticipated bitcoin price in order to get some ideas regarding how many BTC that we might be able to accumulate of the situation, yet we can ONLY approximate, and it might look something like this:
I understand that some folks might consider these numbers to be overly pessimistic (bearish), and so you can create your own chart and put your own estimated numbers in there. You can also attempt to be more granular about it too, if you like, yet from my own experience, there can be some value in regards to attempting to be somewhat general in future projections and then just tweak them from time to time as time passes (such as where the future becomes the past and then the numbers become known).
