Investing aggressively in Bitcoin is not a good decision. It has the potential to cause you financial loss.
I disagree with you that buying bitcoin aggressively when you can will lead to financial loss if you do it within the size your discretionary income. The level of your aggressiveness is what matters a lot. For example, if I have $100 and choose to invest $80, provided I am not just starting my bitcoin investment and have backup funds on ground. $80 wouldn't make me run at loss or sell my bitcoin when it's not my will because I still have $20 left from my discretionary income.
It's when you buy over aggressively outside your discretionary income that will make you sell your bitcoin when your needs arises if bitcoin price is below your entry point. The most important thing is that you should have good cash inflow management practice. Investing aggressively gives you the opportunity to build your bitcoin portfolio in a faster pace for the future, which is good. To front load your bitcoin investment is also good.
Yes, you are absolutely right. Aggressive investing is not harmful for everyone. Before taking an aggressive approach, you must ensure that you have your backup funds ready and sufficient cash flow in reserve. If you then have the informed capital to take an aggressive stance, why shouldn't you go for it?
Another important point to keep in mind is that your consistency must not be disrupted by becoming aggressive in your investments. First and foremost, you should prioritize the DCA (Dollar-Cost Averaging) strategy. Once you have mastered that and are capable of handling more risk, you can move into an aggressive mode without any harm.
An aggressive investment mindset can help you reach your goals faster and build your investment fund more rapidly. Therefore, with proper planning, I see no harm in being aggressive in investing.
