Then the value just diffuses in the whole economy, ending up in investments in countless industries.
Instead you can keep it in stocks of companies you believe in, like startups and interesting moonshots.
It all ends up with the question - do you want the economy to decide where to focus the value (the diffusion) or do you want to decide yourself?
But if you have this amount of money in the first place, you are statistically in the better place to decide than the economy.
