Buying aggressively all the time is not a good idea. Because if a person buys aggressively every time, if he needs some amount of money, then maybe that person can get very broke. For example, if a person invests with 80% or 90% of his discretionary income all the time, then when there is a small financial crisis, he will have to depend on his emergency fund or take a loan from someone. But yes, how much % to invest is completely their personal choice. But I think it is right to invest 35% to 45% of your discretionary income. Because it will not be too aggressive and not too low.
You can continue to buy continuously by adopting the DCA method and if you see a decline in the market, you can buy aggressively if you want.

so buying aggressively shouldn't be base on their is dip rather than the level of your Discretionary income.
if you know that your discretionary funds is large enough for you to be buying aggressively regardless to the market condition, of course you have all the right to do so, but this is not about having a large discretionary fund, you need to ensure that you have a good cash flow, because I know you're indirectly referring to Micheal Saylor who have been buying aggressively without considering the market situation, That is because he has a good cash flow, which is why he was able to maintain his buying method, So anyone that does not have the capacity shouldn't be looking at Saylor's buying method.
