This whole line of thought came about because someone made fun of me for spending Bitcoin because they said it's stupid to give away Bitcoin, as if you keep it, you'll be much wealthier, later.

Which ticked me off because it's obviously untrue and small-minded, but I had to think a bit, to formulate why it's untrue.

It's untrue because the Bitcoin you spend doesn't disappear. It's a closed, stable system where all the money that will ever be already exists. Bitcoin flows around and leaves things in its wake, so that those things are added to the Things Encompassed by Bitcoin and the value of all Bitcoin rises.

This is why spending Bitcoin can increase your wealth, even if you do not get that Bitcoin back:

MONEY IS NOT WEALTH.
