There are many advertising networking is active right now but I don't have much experience in advertising on these crypto advertising networks.

These networks are paying based on what I heard from other bloggers but since you are planning to advertise I'm sure that these networks are trusted to advertise.

Here's my list below.

- coinzilla.com
- mellowads.com
- A-ads.com

Another list of the advertising network but they are not accepting bitcoin payments. However, they are most trusted networks.

- http://www.media.net/
- https://buysellads.com
- http://www.google.com/adsense (caution this is not accepting crypto related niche)
- https://bingads.microsoft.com/

CPA or Cost Per Action or pay for affiliate everytime they sold they can get commissions. The good thing here you don't need to pay for CPM you will pay only for Cost per action.

- Maxbounty
- Peerfly
- Jvzoo
- clickbank

I hope this list helps.
