Above image portrays a tweet made ten years back. By that time Greg Schoen have sold his 1700 Bitcoins. When the tweet was made, the price of bitcoin is $8. He had sold his holdings for $0.30 per bitcoin. It is a missed opportunity, because he wasn't able to sell at $8 as well as at the present peak. But, he's good enough to talk about cryptocurrencies. Now all he have is ethereum and few other altcoins and not bitcoins.

If there are similar people with verified information about missing opportunities to make good profit out of it. Please share it with the image on the thread.
