I assume USD on exchanges or withdrawn USD count as positive balance, and voted accordingly. That would phrase the question as "What is your current profit balance, with everything converted into USD?"

What I believe is that the main sources of funds are people buying in for five-figure sums or more, while the main drains are speculators who sell when it gets too risky and miners/early adopters who cash out at arbitrary times or whenever they don't expect a further rise in value.

It's not so certain the important players (speculators, early adopters who bought insane amounts back in the day) will disclose a lot of info; and even if they do, the vote won't say much, since it caps at 10k$. I think the only people who have fairly reliable distributions are those working at mtgox.

I've not invested anything.

I've bought a couple of coins, but that's to learn about them and to use them because they seem like they could be a useful commodity - not because they are an investment vehicle.

During the hype i bought 20 for 15
After red friday i sold 10 for 11
