Again we should understand what buying aggressively mean; It can mean large capital allocation or purchasing at a high volume. And a discretionary funds are funds that is left over after all the expenses and bill payments. One must be a high income earner to say he’s buying aggressively with his discretionary funds.
You must not be a high income rather to buy aggressively. Aggressiveness is the measure of the quantity of your discretionary income that you invest into Bitcoin without overdoing it and causing stress to yourself in the process.
Aggressiveness is investor specific, and an investor can be more aggressive than the other while not necessarily investing a higher amount than the latter .
For example, an investor who has $300 discretionary income on a monthly basis and chooses to invest $180 out of it into Bitcoin which is 60% is more aggressive than another investor who has $1000 discretionary income monthly and invest $500 into Bitcoin which is 50% irrespective of the fact that the second investor puts more funds into Bitcoin. This is because the first investor puts in a higher fraction of his discretionary income into purchasing Bitcoin therefore he shows more aggressiveness in his accumulation journey.
