I responded so your image would be visible.
I am not sure if any of us has to believe in BTC.. that sounds like religion.
It is good to have a plan and then to try to stick with our plan, and ongoing buying of bitcoin seems like a good plan.
I personally prefer weekly buys rather than daily buys, but surely I can understand that if a guy is still early in his bitcoin journey, he might initially establish his position with daily buys.
It is acceptable for everyone to buy Bitcoin DCA method weekly, but Bitcoin investment is useful enough according to the person's ability not daily to be self-sufficient. I noticed it started buying bitcoins from November 2020, but I think it is capable of holding for a long time. Because it is possible to hold Bitcoins depending on the situation, DCA method is the most convenient and easy to hold Bitcoins.
A long-term Bitcoin investment can result in long-term sustainability, but the Bitcoin DCA method is most useful on a weekly basis, and Bitcoin purchases are within the discretion of holders.
I think you are getting something wrong especially with the DCA method of Bitcoin accumulation. The DCA method is not a method used for holding Bitcoin but a method use for buying Bitcoin in such a manner that it is done regularly with smaller amount than the total budget for purchasing Bitcoin. You can put it that instead of buying at once with all the money you budget to buy Bitcoin, you can divide the funds into many parts and purchase one part at a time within a range you have decided for yourself. If the funds are not readily available but your cashflow is predictable like salary, then the DCA method can be applied.
It is important to understand that the DCA method is not the only method for buying Bitcoin even though it is one of the popular method. A lot of people seems to lean towards the DCA method because of the simplicity it has for all income classes as it gives everyone the sense of confidence and the feeling that they are doing the right thing.
Holding Bitcoin for a long time has little to do with the method used for buying them rather there are more important ingredients that makes it possible. Some of them is the provision of emergency funds that takes care of unplanned events that must be attended to and the idea of making investment with only discretionary income. These two factors will help the investor more with regards to holding Bitcoin for long.
