I think 0-10 is a too large a range. There's a big difference between having $10 worth (~0.07 BTC) and $1500 worth (~10 BTC). The first is what I have, which is basically play money. The latter is a more significant investment.
With that said.... I said I have zero in the poll.
A charity proxy would be cool though, that way people like us have the ability to only donate .0005 and the people with 10,000+ can donate too. Then the proxy converts it to real money and donates it to a particular charity.
At first glance it seemed to me this poll said pretty clearly that HN doesn't trust BTC (and to an extent, it still does, it just softly suggests it rather than shouting it with irate certainty). Having this context makes the result less interesting but at least frames it appropriately.
I'm in a position where I can wait for the next massive crash and buy up maybe 10 or 15 as essentially a form of gambling. Because why the fuck not.
