You can not say that anyone can decide to invest Aggressively anytime and also talk about being consistent withe the aggressive investment. Investing consistently is best by DCAing with your Discretionary income. When it comes to aggressive investment, it's either you earn an additional unplanned income or there's an increase in your regular income. Excessive aggressive investment could also hamper your assets holding time. It's better to invest intermittently aggressively while maintaining your regular DCA approach in order not to run into financial stress that may lead to premature selling of your bitcoin stash.
I want you to know this about aggressive investment and know peace: as long as you are investing in bitcoin consistently with any amount of money that seems okay for you to invest in bitcoin, you are already investing aggressively. Using additional unplanned income to invest in bitcoin aggressively is another form of aggressive investment that gives you the chance to increase your level of aggressiveness.
The way you guys are saying this , it's as if buying aggressively is a bad thing to do when investing in Bitcoin, in my own opinion, it's a very good thing to do
as long as you are doing it from your discretionary income, where it is bad is when you are over doing it or doing it when you have not finished taken proper care of yourself and other basic needs, that's when it's not good, but if it's done in the within your discretionary income, their is nothing wrong about that.
And take note that you can also do it with an additional incomes that comes in suddenly after all your basic needs has been sorted out, as long as it's done with a discretionary income, then it's ok in my own opinion.
