From following the "how to get bitcoins" link from the demonoid link above:
"Bitcoin services are not highly regulated so a service can continue operating even when it is widely believed that it is insecure or dishonest."

This sounds like it might be a good candidate for the next HC money grab. I wonder what the exchange rate is, i.e. how many karma points per bitcoin.

I've already exchanged my karma points for upload credits, ended up wth a ratio of about 2. If HC ever rises again, I'll be looking to exchange that "2" ratio for a ratio of "1", fair warning.
