Actually, the one thing we know for sure is that she/they/he are NOT swimming in pools of money. It's all right there on the blockchain.

Not a single penny of this person(s) wealth has yet been touched!

This means one of two things:

1. They/she/he is waiting for their BTC to be worth FAR more than it currently is before they're willing to touch even a fraction of it. Meaning they anticipate enormous valuation increase within their lifetime.
2. Bitcoin was a gift to the world, and the creator will never touch any of the wealth. The implication being that it was - and always will be - an utterly selfless act.

Given just HOW MUCH wealth they have, scenario #1 seems exceedingly unlikely to me. If you have millions in BTC, what's the harm in cashing in a few thousand to buy yourself something nice?

Again, NOT ONE PENNY has been touched! Take from that what you will.

The conclusion I must draw, as a man of reason, is that the invention of Crypto was a selfless act - a gift to the world just like Newtonian physics (Isaac Newton was paid only in books for that revelation).
