Can I claim vindication on this matter now? EFF now says:
We don't fully understand the complex legal issues involved with creating a new currency system. Bitcoin raises untested legal concerns related to securities law, the Stamp Payments Act, tax evasion, consumer protection and money laundering, among others. And that’s just in the U.S. …
We don't want to mislead our donors. When people make a donation to a nonprofit like EFF, they expect us to use their donation to support our work. Because the legal territory around exchanging Bitcoins into cash is still uncertain, we are not comfortable spending the many Bitcoins we have accumulated…
People were misconstruing our acceptance of Bitcoins as an endorsement of Bitcoin. We were concerned that some people may have participated in the Bitcoin project specifically because EFF accepted Bitcoins, and perhaps they therefore believed the investment in Bitcoins was secure and risk-free. While we’ve been following the Bitcoin movement with a great degree of interest, EFF has never endorsed Bitcoin. In fact, we generally don’t endorse any type of product or service – and Bitcoin is no exception.
Now you can donate to Singularity Institute using Bitcoin.
Currently Bitcoin mining appears to be profitable as only bubble economics can be. Already some Less Wrong users have purchased GPUs and started mining Bitcoin. Please consider sending some Bitcoins to SI at address 1HUrNJfVFwQkbuMXwiPxSQcpyr3ktn1wc9
2014 Edit: Please donate Bitcoin by using the Bitpay link on MIRI's donate page. Thanks!
