>Olaf Carlson-Wee and Balaji Srinivasan estimate that at a price of $200,000 per Bitcoin, more than half the world’s billionaires will be from cryptocurrency

This misses a key piece of information. They take the price as an an assumption for their argument, but that is insufficient to draw this conclusion. When Bitcoin reaches $200,000 is also a factor.

The worlds existing billionaires will not sit still. If it takes 70 years then it would be pretty easy to make better money elsewhere. I have no idea if or when it will happen. I'm inclined to think on average it will increase at a decreasing rate.

there are people who also believe gold will reach $100k an ounce. I don't think that will happen, or if it did, society would've transformed so much that there bears little resemblance to today's world.

it will take so long to happen that such time frames are irrelevant to anyone alive today
