investor should have their target and invest according to their financial capabilities one don't need to be over aggressive cause their friend who's an investor is doing so whereas they're not very financial strong to do same, it doesn't matter whether one is a beginner or not once one is very financially stable to invest aggressively and understands the concepts of it then follow it amicably then they're good to go so far they don't go against the concept of Bitcoin investment while trying to be aggressive, some investors make the mistake of imitating others instead of investing according to their financial capabilities. For instance, the fact that Saylor at some point was investing daily doesn't mean that investors should do so too just cause they look up to him as a mentor or so whereas they can't keep up with buying daily, that's why I said ever investor should do so according to their financial capabilities.
I agree with you mate, investing in bitcoin is not a competition and shouldn't be, because we have different income and different expenses. Even someone receiving the same income with you will have different expenses and discretionary income. This is why you don't use more than your discretionary income to invest in bitcoin so that you don't end up selling it at loss to take care of your needs when it arises.
Anyone that buys bitcoin over aggressively because he's into competition is gambling and not investing. This is why one need to be very careful in his decisions and steps he takes to keep his bitcoin investment ongoing overtime, so that he doesn't make any mistake that can make him lose part of his bitcoin portfolio.
If you have the financial strength to invest aggressively, do so. But if you don't have, don't try it. It's better that you find a means to increase your income in order for you to have the financial strength to invest aggressively overtime.
