What's the motivation for the twins to hold so much bitcoin? They're already taking on a lot of risk with their BTC business investments. Is it just to show faith in themselves and the coin? Or are they so confident that it makes sense to them? Personally I'd want to diversify.
They bought a lot of bitcoin before the late 2013 bubble. I think they're quite diversified - they're just Bitcoin proponents who are taking a chance, kind of like venture capitalism.
