I'll just mention names of few advertising networks which are most popular and trusted:
Coinzilla, Cointraffic, A-Ads, Bitmedia, Bitcoadz. You won't make mistake by choosing one of these advertising networks.
If you *do* like faucet audiences, freebitco.in and moonbitco.in are as good as it gets.
Small correction - it's not possible to advertise on Freebitco.in
Google Adsense is for publishers only, Google Adwords is for advertiser. But if you read OP more carefully you will see that he already tried it, but Google blocked his ad because it's crypto related what isn't allowed.
