Focus on making lots of reffson trusted sites.
I make around 80k - 100k satoshi daily just from reffs on my top 30 Crypto faucets/ptc/gpt sites.
Keep re-investing to get more refferals. My top earning sites are - Moonbitcoin, Freebitcoin, Bonusbitcoin, AdbtcTop, FaucetPay, FaucetCrypto, Cointiply, FreeTether, MoonDash and MoreMoney.
Good luck.
I also have the same strategy but find it hard to get quality reffs, as usually they will claim one or two days and leave. So far, the best one for me is FaucetPay. AdbcTop is also paying well but their clicks campaign suck and convert at about 0,50% as traffic is mostly Russian. For the meantime, I am a little bit disappointed with Cointiply which is often considered as the best one.
I have some sites with more than 300 reffs which bring only xxx satos a day, which is pitiful considering the bucks you invested in the campaign.
The main difficulty is to have the good connection between the source site (ie the campaign) and the target site where you will get your reff and more important where they will keep on claiming. You could also have some split testing sending the campaign directly to your own website and check the "quality" of the visitors since having Tier1 traffic with that kind of campaign is really pain in the a...
Meanwhile I know those sites could be a good springboard for more serious income using Tier2 networks. I would be interested in sharing with you some strategies I experimented.
PM if ever you want.
