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.
Why don't you talk in terms of your own experience rather than abstract concepts about how DCA is so great blah blah blah... Have you even started to buy bitcoin or are you just theorizing about it?
