I believe a similar number can be derived by figuring out how much bitcoin would be needed to claim to be in the wealthiest 1% of world population. I think once accounting for lost coins, the number ended up being around .25 bitcoin. I made a point of securing at least that much for myself and each of my children as an early stacking goal.

That's the real magic to it - if it helps you by giving yourself a goal to work towards, then it might be priceless, regardless what the actual number is.
