What would happen if you sold everything you own, liquidated any investments you have, paid off all of your debts, and withdrew whatever cash you have in bank accounts?

You’d be standing on the street naked, with nowhere to go, holding a bunch of cash, and people would be looking at you.

holding all your net worth:


And whatever cash you were holding would be your net worth.

Okay now, imagine that everyone else in the world does that too (just pretend that makes sense), and all the people of the world, naked and holding their wealth in cash, come together and throw their wealth into a big pile together. How much money would be in that pile?

$241,000,000,000,000.

The combined wealth of all the people of the world is $241 trillion.1

So at this point, the whole human race would be standing there together, all naked, all broke, looking at a massive pile of cash.

The world's wealth in hundreds:


Okay, the maximum number of bitcoins is 20999999.9769 BTC. Of course, it only differs from 21 million BTC by only 3 bitcents, so the difference isn't significant.
So if we divide the total wealth on total btc it will be $12,050,000 it means if the world accept bitcoin the value of one bitcoin will be $12,050,000.
You may be a millionaire in future
