In my opinion a good investment portfolio requires longer time and it is necessary to purchase Bitcoin regularly. Moreover building an investment portfolio requires a lot of patience, time and need to keep themselves steady during the market updown. As you mentioned that buying a little more aggressively when the market is a dip, it is okay but buying it aggressively may have to be considered on your financial ability.

Because the amount of money we budget for our regular Bitcoin purchases comes primarily from our disposable income, that is, from the money in our budget set aside for investments. So I think it might not be wise to aggressively invest all of your hard-earned money as a result regular Bitcoin purchases may be temporarily halted.
