“The best estimates currently available suggest that around 205,238 tonnes of gold has been mined throughout history, of which around two-thirds has been mined since 1950”
Visual Capitalist also has a great series on gold. It's now 10 years since it was published so some of the numbers are off but still lots of intersting info!
And Aker, a big company in Norway, created Seetee, a company focused 100% in Bitcoin. Here's the Shareholder's letter from the CEO of Seetee, it's a great read, it describes how he personally discovered Bitcoin and how he's trying to learn as much as possible and move towards the future with Bitcoin.
Today we announced that Aker has established Seetee, a new com-
pany that will invest in exciting projects and companies throughout the
Bitcoin ecosystem while keeping all of its liquid investable assets in bit-
coin. The new company has a capitalisation of NOK 500 million, an
amount we aim to increase significantly over time as we gain experience
and identify exciting opportunities
Gold could fall like a rock any day imo due to asteroid mining.
And that's easier than you might think. All the gold mined on earth fits in a cube with 22m sides - any asteroid could easily double the supply. And the mining process would just be stiring an asteroid slowly to fall into the desert.
But it gets even easier than that: Markets are forward pricing. All it takes is Elon tweeting that he wants to do it and markets will price that in.
