A bitcoin investor mustn't be very very aggressive in hoarding bitcoin yes their are times for that, for instance when opportunities of the dip arises but it doesn't involve waiting for it to occur before buying, the DCA is already there to make sure that every investor maintains consistency and still meet their target so being very aggressive doesn't always matter the goal is to maintain consistency over a longer period.
Being aggressive matters a lot as it's a measure of your determination to reach your accumulation target as quickly as possible. You should understand that it's still very possible to be consistent and whimpy at the same time and when you're overly whimpy, your success rate is low and you don't treat your investment with as much commitment as supposed if you'll be honest with yourself.
Let's take for example, an investor has $100 weekly discretionary income and he invests only $20 into Bitcoin leaving out $80, such investor is whimpy and less aggressive compared to another investor who invests $60 weekly into Bitcoin. You'll see that the second investor shows more dedication and commitment to his investment and stands a better opportunity of reaching his accumulation target and possibly arrive at a state of over accumulation much earlier than the first investor.
The dedicated investor would obviously have 3x more the quantity of Bitcoin than the first investor if they've the same holding period. Obviously, upon having more discretionary income available, the aggressive investor would likely get move aggressive with his investment while the whimpy investor might not even consider increasing his buying amount since he's more focused on consistency like you mentioned and not the effectiveness of his accumulation of Bitcoin.
It's important you get as aggressive as possible in your Bitcoin investment without overdoing it in order to record a high success rate in your accumulation journey
