Buying aggressively is never a bad thing if it's done within your discretionary income, it's a healthy practice used to increase the stash of your Bitcoin faster, where the problem lies is when you are doing it from money meant for your basic needs or money that is not your discretionary income, if it's within your discretionary income, I don't think anything is wrong about that because your emergency and reserve funds are there already to bail you out in case of any emergencies that may arise in the future.
Additionally, those that are at the beginning of their accumulation journey are those that needs it the most because they are seriously lacking behind, but it should only be done within their discretionary income, as long as it's done that way their is no problem about that.
you are correct buying bitcoin aggressively is not a bad thing provided you buying it within your Discretionary income and not with your emergency fund or with the money met for settling your basic needs and your expenses. In my own opinion Being aggressive becomes bad when you are buying bitcoin with your emergency or with the money met for your basic needs and expenses, because it can endanger your bitcoin investment and can make you sell off your bitcoin investment at early stage of accumulation in lost. Less assume someone want to be aggressive in buying bitcoin and then went head to buy bitcoin with his or her emergency fund and emergencies arise along the line so which fund do the person intend to use in handling those emergencies since he or she has already invested his or her emergency fund in bitcoin all in the name of trying to be aggressive in buying bitcoin. Or less say someone bought bitcoin with the money met for his or her basic needs and expenses, so tell how those the person intend to sustain and still able to hold his or her bitcoin for long term? If not selling off his or her bitcoin investment in easily stage of accumulation in lost. The truth is if an investor is consistence in buying bitcoin he or she will definitely reach his or her accumulation target, so instead of endangering your bitcoin investment all the name trying to aggressive in buying bitcoin, just be consistence and committed.
I disagree with you on this. Emergency funds isn’t for investment, first you’ll have to understand what emergency funds is which I’ll define it; An emergency funds is savings set aside for unexpected expenses or financial emergencies for example, in the case of losing your job, medical bills, car repairs and all that. No one is his right senses would think of by Bitcoin aggressively with an emergency funds. A real investor understands what discretionary funds are and what emergency funds are, and as such can’t mix both together, because it’s serving a different purpose.
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.
On hearing the name "emergency funds" one should understand what it's mean you, yes an emergency fund shouldn't be used for investment, it's main purpose is to serve as an available money to solve problems in times of emergency, as humans we should be prepared for a worst case scenario, therefore an emergency fund is meant to be set aside for cases like that, it's very different from the funds used for investment.
Although sometimes it can be very tempting to use the emergency funds to buy bitcoin when the market dips but as an investor you should be disciplined enough to know the right thing to do and it's never investing with the emergency funds, the funds that's required for investment is the discretionary funds.
