If you receive salary monthly and you think by dividing the money you have set aside for your Bitcoin accumulation into weeks will earn you more Bitcoin through the hope that there will be a dip within the week were you can buy at low price then you are just a trader.
Have you thought of you dividing it and in the course of you buying weekly with the money met for the month and Bitcoin price goes up will you wait for it to come down before you buy or you will still go ahead and buy, there's no need dividing it if you receives your salary monthly because there's no difference in the monthly and weekly accumulation except you are a trader who is waiting for a dip to happen
as a short-term trader that will be a nice strategy but not for long-term investors, because waiting for the dip is not a smart move at all as a long-term investor , rather you purchase at anytime you have some money to spare that you can hold for long either by DCAing or lump-summing.
Because waiting for the dip will only slow one down , and IMO the when it comes to accumulating, whenever I divide my funds, I usually use 40\50 , so the 40 percentage Is my emergency funds while the remaining, is for accumulating, in order to cover some space but is not fixed though, because sometimes I can choose to set some percentage as reserve funds but I mainly focus on emergency and accumulating funds .
