When I first got into bitcoin, I was actually buying every week with my set budget and also trying to find dips within the week in order to maximize my BTC buys for each of the weeks within my set budget for each of the weeks, but most people are not that passionate, and they might well be better off by not being passionate, and just exercising "set it and forget it" so after a year or two, they look at their investment rather than watching it every week like I had been doing and maybe many of the active forum members are willing to do... but normies do not necessarily want to be very active in terms of their BTC investment and that is one of the reasons why DCA can be so powerful for normies who do not want to study or watch their investment with any kind of particularity.
Actually this was the same kind of buying strategy or rather method by brother normally use for accumulation of Bitcoin, what he does was that he will have a targeted amount of Bitcoin to be accumulated within a month and with the strategy of watching the market all the time to buy from any little dip he sees so that's the kind of strategy he normally use, according to him he said the method allows him to minimize the amount of money used in accumulating Bitcoin.
What I understand from this method is that it has to do with a lot of patient and consistently watching the market in other to have a good entry, so is very stressful method and I can't imagine myself using that strategy but however irrespective of the little advantage it may have but it can never be compared with DCA method, because it allows you to set a target and hit it without considering the price movement.
The strategy that I am describing is pretty damned close to DCA, especially since I was doing it on a weekly basis. Let's say, for example, I had a budget to buy bitcoin of $100 per week, and it was for 26 weeks (which would be $2,600 for 6 months). And if the beginning of the week is Monday and the end of the week is Sunday, maybe I might identify a couple of the dips through the week or maybe I would be waiting for dips that did not end up happening, so by the end of the week (Sunday) I would use either the whole $100 or whatever parts were left to buy at that time.. of course, the beginning of the week could be chosen as any day. and each week there was a new $100 authorized, and let's say that I felt that I did not have time to watch the market, so maybe I would just buy or maybe the price opens at $28,500, and I would set my buy order at $27,820, and if the order did not fill by Saturday, then I would just market buy or maybe set the buy order within $50 of the current price so that I have more confidence that it is going to fill before the end of the week.
