You seem to be arguing and quibbling with the main points that I was making, which was to rebutt your assertion that investing does not give up anything in the current time, which it likely does, and if it does not then you may well be investing way too whimpily.
Sure your level of aggressiveness is a choice, yet your earlier blanket statement that investing into bitcoin does not contribute to giving anything up seems to be factually wrong, whether a person is investing whimpily or aggressively, and even if he ONLY invests $10 per month, he is still giving something up by dedicating that amount to bitcoin rather than buying a couple extra cups of coffee... or however he might have chosen to otherwise spend or use or save the $10.
That's not what I meant and moreover I support everything you have said in the post I quoted, but in this case you might interpret it in another direction, so sorry if that makes you upset. But I always support every point you have explained and I want to strengthen it with my explanation, perhaps what I explain is a bit difficult for other people to understand.
I support what you said in the previous post that they act aggressively to buy bitcoin by selling cars and saving their monthly expenses to invest in bitcoin. And here I just add a few points from my idea that if they are beginners who invest all their income, of course they are not ready when everything happens to the market, for example a 50% drop.
As for the second point, I also support your point, when they get additional income, of course they can use that money to buy bitcoin aggressively ( when they get additional income).
On the other hand, I support everything you have said and there are many useful points for those who are beginners in investing in bitcoin. They can start from $10 or depending on their ability to manage their cash flow.
