Earlier quoted context omitted.
He actually put in $300k, so his shares are worth around 2.4 billion now
Did he? If he simply bought bitcoins with his $300.000 in 2012 (average bitcoin price of $8) then his net worth now would be .... 37500 bitcoins or $2.362.500.000 ... 2 point 3 billion frigging dollars...
You phrase it like he made a mistake and lost out on a huge profit but the ROI is exactly the same so really don't understand your comment.
