actually it doesn't matter how much you buy btc and at what high value you stop buying it. 'IF' you have free funds
Having a good and accurate portfolio is everyone's dream because it can reduce the impact of unexpected events
That "if you have funds" makes the difference I guess. Many people would like to have more (including me, of course) free money for investing in different things, as you say, having a good portfolio is everyone's dream! But how many people actually have that "free money"? Most people live from month to month, or in the worst case day to day, and it's really hard to put some "significant" amount of money aside.
Each of us is in a different situation. I have two little kids and I am trying to finish the house, expenses are big... the prices are going up! It's a bit hard to keep up, and when you get into some "big projects" the money is just flowing away, sort of speaking...
And for sure we all want to reduce the impact of unexpected events and unexpected expenses, but shit happens. It's life!
