I disagree with you mate, you don't need or have to get an additional source of income before you can be aggressive in your investment, aggressiveness is a function of how big your discretionary is or aggressiveness is as a result of strong discretionary income. Remember when you are Investing aggressively you don't need to touch any other funds than your discretionary and anything that makes you touch other funds is a wrong thing or wrong approach because it's only our discretionary that is meant to be touched while we carry out Bitcoin investment whether aggressive or not. All an investor need to do before investing aggressively is to build up a good and huge discretionary and everything is settled.
I have To Disagree.
Having a steady source of income before going aggressive is very crucial because discretionary funds don't just appear out of nowhere. They are created and replenished by Steady Income. If someone invests heavily without securing a secure and sonsistent cash flow their "huge discretionary income" can dry up very quickly and when the Market Dips, They may be forced to touch other essential funds (which you rightly said is wrong). A strong income stream provides with sustainability and flexibility in aggressive investing, while also protecting against the risk of running out Investing capital.
We don't need a fixed income to be aggressive in investing, what we need is a source of discretionary income. You need to find a source of discretionary income through proper financial management. You need to continue investing with your discretionary income source and if you are willing to buy aggressively then you can buy aggressively depending on your financial situation.
If you buy aggressively without depending on your financial situation then you can face many kinds of problems. For example: Financial crisis if you buy aggressively with the money you need and if that amount of money is needed after some days then you have to sell your investment. In this way it becomes very difficult to maintain the balance of your investment, so it is better to continue investing depending on your financial situation
