Isn't that obvious that he's just making an assumption? Moreover I think the wise and the rich are the ones that engage themselves in buying bitcoin aggressively the most, reason is because they have a steady source of income that they can use to load thier discretionary income so as to enable them invest with any amount they wish to go with
A good investment strategy starts with how you manage your capital for investment and other things beyond investment including emergency fund. Then in investment management, you don't need to purchase bitcoin aggressively, it has nothing to do with your success. A good strategy is invest what you afford to lose, with capital you feel most comfortable for your investment. If aggressively purchases mean something like loans, leverage, it's not good strategy.
I'm obliged to thinking that your main confusion stems from a poor understanding of discretionary income. Now discretionary income, also referred to as cold cash is the money remaining after you must have sorted out your expenses and needs, leaving some funds you would not be needing anytime soon. These funds you would not be needing which would've just been stagnant is what you are advised to invest into bitcoin. You need to purchase bitcoin aggressively if at all you're serious minded and you have the desire to reach your accumulation target ASAP or/and even attain a status of over accumulation within your holding period which is a very good thing. Being aggressive without overdoing it has everything to do with your success in bitcoin because when you're aggressive, you tend to purchase more bitcoin within a stipulated time and in bitcoin, the success formula is very simple "
the more quantities you've got, the greater profits you enjoy".
The backup funds serve as a protection for your investment and in accurate cashflow management, you need to build it alongside your investing into bitcoin, and all these should be done from your discretionary fund alone.
Of course, you should invest what you can afford to loose in bitcoin since there is no guarantee on your investment, yet when it comes to success in your investment, the whimpy investor does not come close in profitability compared to the aggressive investor.
Investment success has nothing related to your investment capital like whether it is big or small. If you invest in a right asset with good strategy, you get great investment ROI, and that means your investment success and profit.
Bitcoin is the right digital asset for you and as of now, when you buy bitcoin consistently with a bigger DCA amount, your success potential is higher than the person who was overly conservative in his purchases.
