Of course, frequently risk can be compensated by position size, and of course, if you end up being too whimpy in your BTC investment because you are afraid of downside risk, then you still will end up profiting, just not as much if you had been more aggressive in your investment, so you can choose your level of whimpy versus aggressive and have to live with the consequences either way.. which still ends up being better for the whimpy investor rather than the no coiner.. .. even while there are no guarantees of such.
Aggressiveness is fine in investing but I don't think there is any need to be aggressive when it comes to holding your investments for a long time. Aggressive means that the investor will not think twice to sell his investment, I think if he is so aggressive he will not be able to hold his investment for long. Before investing, when the investor thinks too much about what time of the market he should invest, what time he will invest, when he wastes extra time, basically the investor should be aggressive for that time.
An investor can invest aggressively and still not get affected, especially when he didn't over do it i.e he invested aggressively and still have his emergency funds and every other important needs available. It is just like I decide to invest $100 into bitcoin with ease and it will be as if I am not putting in money into somewhere. I can decide to increase my regular DCA amount to $200, but with this, I have to trim my expenses so that it wouldn't affect my monthly expenses and I will still have reserve funds for other purposes instead of me still investing with $100 because I want to be buying other things that are not necessarily needed.
If you just started your bitcoin journey, investing aggressively is good as long as it wouldn't affect you so that you can use a short period of time to have a significant amount of bitcoin. It is when you over do it, that is you invested with almost all your weekly income, forgetting that you will need funds for some financial needs that is when you will end up destroying your goal because when you are short of funds, and an emergency arise, you will be forced to sell your bitcoin at a price of is not of your will.
