1. Nope. I see no need to and I don't really think fame would get me anywhere. In fact it'd only be a bother really. I'd rather let the status quo remain.
2. It depends? I mean if I'm in need of money why not. Not all of a sudden or all at once though. I'd much rather do it slowly really. Said BTC ain't going anywhere anyway and no matter the price change, it'd still be a sizeable amount no matter what.
3. Definitely.
4. No. That goes against what I said with 1.
5. Yes.
6. Nope. Maybe at my will, but I see no reason why I should reveal it willingly really. Maybe if they were able to trace it somehow, then sure why not.

Revealing himself seems just a recipe for disaster or chaos really. Just the fact that he owns thousands of Bitcoin is enough of a factor really.
