I currently have a BuySellAds.com account that I want to withdraw my advertising balance from but this is not allowed. So I am selling ads as a proxy for 10% less than their listed price for bitcoin.
You can advertise on sites such as:
CoinMarketCap - Available from $14.4 CPM for 728x90 top banner
CoinJournal - Varying ads available such as 468x60 newsletter for only $100 USD
And more, see here:
https://www.buysellads.com/cartCPC Available upon request. Splash campaigns from $1.25 CPC which I will offer for $1.20 CPC.
If you are interested in buying the entire account, it has a $7k USD balance. I will let it go for $6k USD worth of BTC.
Thank you
