Buying aggressively must be with careful calculation, I agree that it is never too late to enter Bitcoin, especially to invest in the future, but I do not recommend buying aggressively without calculation.
It would be better if we apply a strategy and do it consistently, the DCA strategy may be the best option if we want to invest in Bitcoin in the long term because if we look at the history in the past, I think all of us here have no doubt that the same thing will happen again in the future.
If we are confident with bitcoin, in my personal opinion, whether to buy aggressively or with a gradual strategy like DCA, I don't think it's a problem, as long as the funds invested are discretionary income, I think that's the important point. Because aggressive purchases or with DCA, it's just a method or strategy that can be adjusted to our financial condition. So if our financial condition supports aggressive bitcoin purchases, I think that's good too and vice versa if our financial condition supports DCA, that's also a good thing. So the point is if we intend to invest long-term in bitcoin, as long as we use discretionary income,
I don't think it matters what purchase strategy will be used. Because basically it ultimately leads to the same goal, which is long-term hodl. So the point is we have to be more flexible regarding the purchase strategy that we will use when investing in bitcoin. And don't assume that other purchase strategies are not good enough. Because the point is if everything is done with discretionary income, the chances are it will definitely be fine.
Of course, it will lead to the same goal because you all plan to invest in a long term, but the results will be different in your bitcoin achievement in the long run, because who bought aggressively when he can will accumulate more bitcoin than who accumulated in a whimpy way despite the fact that they both use DCA method to keep their bitcoin accumulation ongoing for 4-10 years and above.
A new investor should only stick to using DCA accumulation strategy to accumulate bitcoin with his discretionary income overtime and can mix it up with buy the dip and lump sum. Using any of the three accumulation at strategy wouldn't give you the same results in the long-term, because using only the buy dip method will make you have very little bitcoin in future because you are always waiting for the price of bitcoin to dip before buying which is a waste of time.
If your weekly DCA is ongoing, and you are being given a bonus, or a travel allowance, you can use part of that money to lump sum right away. When the dip comes and you have reserve funds available, you can use it to buy the dip.
