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.
Instead of using the word aggressively you should have used buying bitcoin above your means of livelihood. Someone can have all their necessities covered and still have enough to cover other peoples basic needs and they are buying bitcoin aggressively, they do that because they can afford it.
But if they can’t cover their livelihood expenses and bill, buying bitcoin above and neglecting your sustainability is a bad idea.
