Substantively, it may not really matter so much what we call it, and so each of us have to consider how persistent we are in regards to investing into bitcoin, and surely people have a lot of things going on in life, so some of those people might set up an automatic DCA, even though personally I like the idea of manually executing DCAs, on a practical basis, it can be better for some folks to have their DCA buys (weekly or whatever to be executed automatically.
When you said manually, can you please give some clarification. Because base on how I understand this reply, having a fixed time to purchase like weekly or monthly is a form of automatic DCAing? Just wanna know the different between manual DCAing and automatic DCAing, it really picks my interest.
Even though I agree with you that DCA might not work for everyone, you have not given an example of lump sum, and you have largely given an example of DCA because you are suggesting that the only reason that the guy had not executed his DCA is because he was busy with other things... yet you are suggesting that he still is interested in buying BTC, he just is busy with other things.
I would suggest that a non-DCA approach might be a guy who is not really very seriously thinking about BTC.. so sometimes he thinks about buying BTC and other times he doesn't, so he is erratic based on his own lack of conviction about BTC
Base on my understanding, I will say lump sum is the opposite of DCAing strategy or method. Because it literally deals with one going in at once , without breaking the payment down . Like for instance I have $10k , and I want to invest on bitcoin, I can decide to break it down into 10 places which will be $200 each , and I will have a fixed time to make my purchases ( with the $200) either weekly or monthly, buying at different price interval. Or can use lump sum method by using all the $10k at once to purchase bitcoin without any form of breaking in a fixed time
