For example, you have the money to buy aggressively, but you may not be able to invest with it due to some problems. For example, you are not able to transact due to some problems or errors in the bank where you have deposited the money. You know that after some time or within 2 or 3 days, your bank account will be fixed or you will be able to transact again. But you have to be confirmed that you will get the money after some time. In that case, you can invest for some time with emergency funds.
I would never support buying aggressively because the wise and rich investors don't engage in that due to a lot of mistakes that can be seen buying too much at a short period of time. It is good when we distance our investment strategy and buy at an interval. This is the same DCA strategy that Micro Strategy is using to accumulate thousands of Bitcoin without getting choked up at a certain price. There are so many profits to be made when buying at different intervals, giving a breathing space to buy at different prices.
How did you make up your assertion buddy? Buying aggressively doesn't necessarily mean buying too much. It is the percentage of your discretionary income you commit to buying bitcoin that determines your level of aggressiveness. The real problem stems from being over-aggressive and that is buying more than you can sustain, thereby placing you at a disadvantage. Your level of aggressiveness without overdoing it is a measure of your commitment to your accumulation journey.
For example, Investor A and Investor B both has $200 as discretionary income weekly, Investor A commits 60% of his income($120) to buying bitcoin while investor B only puts in 20%($40) into bitcoin. We can see very well that investor A is more aggressive and serious in his accumulation journey since he commits more part of his discretionary income into accumulating bitcoin while investor B can be described as being whimpy in his purchases. Investor A would definitely have a larger portfolio size and reach his accumulation target much faster than investor B.
