It is not possible for ordinary people to buy aggressively. Many big businessmen take this risk whose financial condition is very strong. We have to take risks considering our financial condition. If you have enough money aside from monthly expenses, then you can invest with that. Before investing, you should first understand your monthly income well. Again, you should understand how much you spend and how much is left. However, it is not possible for any person to invest aggressively.
You seems to have forgotten that buying aggressively does not necessarily mean that you must be a business man or woman, Moreover you're not investing from your business funds but from your discretionary income if your discretionary income is enough for you to start attempting to buy aggressively then you have every right to do so, but should be done according to the size of your discretionary income and not going extra mind just so that you can engage yourself into aggressive buying of bitcoin going about it this way is very wrong but once you're investing according to the level of your discretionary income even if you choose to buy aggressively I don't see anything wrong with that but is always advised to stay within your line and not crossing it.
The point is that ignorance is the major cause of inaction and wrong accumulation approach by most newbies investors and that has what kept them backward or even stagnant in their Bitcoin accumulation journey because they mostly feels that they can't do some certain things because they are not wealthy, not knowing that what they just need to have is the will and the discretionary income to do it.
You will hear something like "I can't invest in Bitcoin aggressively because am not rich" not knowing that aggressive accumulation boils down to how good you are with your money management skills, because their are so many people out there that earns quite a lot of money but still can't figure out their discretionary income because they can't give a perfect explanation on how they spent their money, so it's more about a good money management skills than being wealthy.
