Indeed, i try to promote my referral link in my social media account, but until now no one referral come to me. Its good way to earn passive income but very hard to do it.
You need to realize that nowadays it is hard to gain referrals especially on faucet sites. People are not too interested to claim faucet every hour because they have already known that it is not worth the time.
Maybe you may get some but most of them are not active referrals, they only register and claim few times. It does not give you significant amount. You need to have better place to spread your referral link outside social media pages.
Currently many members already registered and now its very hard to have new for this faucet because some day ago I also try with some ptc sites but response was just zero members which done this in start have very good system and taking good reward for joining this in early days
