use the compromised credit cards to buy more bitcoins
Do you know a Bitcoin exchange that takes credit cards directly, or are you imagining an intermediate step like money orders?
It looks like the one I saw in the past may have folded, as I can't find it. In which case, it might be necessary to use an intermediary, like moneygram. For that sort of large-scale credit card theft, you'd want something fast and automatable, to try to earn the maximum per-card return in the interval before the owners notice and disable them.
Less Wrong used to like Bitcoin before it was cool. Monthly threads popped up around the same time a pricing bubble brought mainstream attention last year. When the bubble popped, and price continued to deflate, discussion on this site stopped entirely. Was there a change of sign in the social status of the topic, is the topic fully explored, or has there simply happened nothing of interest over the last year?
If you are not familiar with Bitcoin, here is one intro I happen to like.
Kaj Sotala lists a number of previous threads on the topic:
Less Wrong seems like a good place to discuss recent developments, if one does not want to suffer the inanity of the officially unofficial forum. If you are not longer interested in Bitcoin, perhaps send your remaining balance to the Singularity Institute?
