I'm building a Bitcoin related website and was wondering what different types of advertising monetization options there are in the Bitcoin space.

Are there any affiliate networks that have Bitcoin related stuff on them? CPA for bitinstant sign ups for example.

last week Coinbase had their program but it got shut down until further notice.

Already have started using Coinurl and also know of BitcoinAdvertisers but I'm looking for more CPA kind of deals.

Anyone any ideas?
