Anonymous Ads -
http://www.a-ads.comProbably the oldest bitcoin ad network still running. Pays based on the amount of views, but is dependant on which advertisers are advertising and their daily budget. I have used this network on all of my bitcoin projects and have been paid by it every time without fail. This ad network is for banner and text ads.
Minimum withdrawal - 0.0001BTC (No fee)
AdBit -
http://www.adbit.coA successor to an older Bitcoin ad network which shut down after the admin went awol, AdBit runs on a pay-per-day bidding system. Basically, you put an ad space on your page, and people bid on it. The higher the bid the more of a share the advertiser has. Due to a spam of one satoshi bids, the default minimum cost per day is 0.0001BTC. This ad network is only for banner ads.
Minimum withdrawal - 0.001BTC (0.0001BTC Network Fee)
Bee-Ads -
http://www.bee-ads.comBee-Ads runs on the same system as AdBit, however their minimum bid is only 0.000001BTC. This ad network is only for banner ads.
Minimum withdrawal - 0.001BTC (0.0001BTC Network Fee)
BitClix -
http://www.bitclix.comBitClix runs on a pay per click system, meaning that every click on your ad gives you a set amount that the advertiser paid for. Can be good if you have a high click rate on your banners. This ad network is for banner and text ads.
Minimum withdrawal - 0.001BTC (0.0001BTC Network Fee)
CoinAdvert -
http://www.coinadvert.netCoinAdvert runs on a CPM (Cost per 1,000 views) system, mixed with the bidding system used in AdBit and Bee-Ads. An advertiser pays for 1,000 views or more for a price you set, and you get paid per view on that ad. This ad network is only for text advertising.
Minimum withdrawal - 0.002BTC (0.0001BTC Network Fee)
BitMedia -
