If you have a really good site with good visitors and a high traffic, you can use Ad-sense account to earn much money by ads. I dont think adsense will make a payment via bitcoin but you can convert the given payment to bitcoin. I think they pay high and have really a good business deal. Many people use adsense for their blog, youtube channel, websites, etc. You can too do the same. You can use it for a month and if you think its not paying high, you can remove the adsense adds. But according to me they pay high amongst all such paying sites.
Adsense does not allow many faucets to use them, which is the reason why a-ads and mellowads are successful against this marketing giant in the first place. If there were no rules regarding the usage of adsense advertising placements on bitcoin faucets then everyone would be using it because it pays way better than any of these services i've listed above. More for info see this article:
https://99bitcoins.com/adsense-apocalypse-bitcoin-faucet-guide-survival/ I'm pretty sure that ePay went bankrupt because of issues with adsense, so thus i don't think it' sa good idea to use adsense at all and risk getting your pay confiscated and account shut down.
epay scammed their users 2 or 3 weeks ago when the bitcoin price increased
