In what sense did you use the word capability here? I understand that not having the ability to invest means 'I have no money at the moment'. Since I have no money at that time, where will the capital for investment come from. So how will a person invest in Bitcoin beyond his ability?

And if you mean beyond his ability - investing beyond his discretionary income. Then where will he get the money to meet his basic needs?
People actually start saving when they have money left after meeting their basic needs.
You certainly don't want us to invest in Bitcoin without eating, without paying electricity bills, gas bills, or paying for our children's school fees.
People actually save so that they can live a good life later. But it is not at all reasonable to suffer more now in order to live a good life later.

Therefore, we need to create such a flow in our life journey that we can live well in the present and use the present time to live well in the future.
