look btc in the investment side of things then you would surely hesitate on spending it up.
I think of it as the opposite.
If we're going to look btc as an investment, we're more worried of spending it because as much as we want to spend, as we treat it as an investment.
We don't want to spend it right away.
I believe, you both are on the same page lol.
Obviously, investments aren't meant to be spend. It's for the future use, especially after you make a reasonable ROI out from it.
Gambling is different, and the main concern in the OP was is it either you're still comfortable gambling even at the highest Btc price or not?
