I was wondering this too, but it seems he is in japan. I think I heard that in japan you can withdraw mtgox to your bank account. No USA banking issues.
I have been trying to decide at what point I will cash out. This assumes a lot...for example optimism that price continues to go up.
Do I cash out now or when I have equivalent of:
1 yr wages
2yrs wages
equivalent value of my mortgage
equivalent value of my mortgage + planned renovations
or hold out to be a millionaire or more?
When I could retire?
Just leave it as an additional retirement funding?
Edit: Also I feel that risk would go up the longer I leave it untouched. From increased regulation, risk from bitcoin failure etc. So that makes me think that I could cash out half at one of the equivalents listed above, then leave the rest longer term, too.
