ok.. if we estimate the largest holding at around 300,000 BTC
(feb 27 2011 richlist shows 250,000 as largest - so perhaps someone will or has amassed 300K or so ?)
Then for that to be worth USD 1Billion - each bitcoin would need to be worth approx $3,333 USD
Even with my tiny holding.. I'd pretty damn happy I think!
I still wouldn't have a clue when to sell though. Perhaps I'd get spooked by $1000 per BTC and take some cash in local currency...
unless by that time I can buy goods in Australia directly in bitcoin

On the philosophy of it.. well.. people inherit millions and billions through dumb luck of appearing in the correct uterus.. so.. it seems fairer that people who take a punt on something as innovative as bitcoin should get a windfall.
