It would be great if this privacy-oriented search engine would consider using this pseudonymous, decentralized digital currency as means of payment for the ads as well.
By using bitcoins, you could develop your own privacy-oriented DuckDuckSense, which would have a great advantage over the current alternatives: pseudonymous payments.
This would allow sites like Weakleaks or others that cannot/do not want to trust the banking system as means of payment to still have some advertisement on their space and be payed for that. Not to mention the much lower fees, the non-need of currency conversion to cross borders etc...
Any chances of that happening one day?
PS: Congratulations for your great work.
