I used to be very interested in faucets when I first started with crypto several years ago. It is a good tool to learn but it takes a long while to earn something good. But if the bitcoin price keeps going up than even claiming 2 satoshis can be worth something big.
If there are still active faucets besides Freebitcoin, these sites can be relevant only for those who attract a lot of referrals. However, it's a waste of time for an ordinary user without referrals because even if the BTC price ever reaches $1 million, 2 sats will be only 2 cents. By the way, the minimum withdrawal amount is 30k sats on Freebitcoin. So, just imagine how long it will take for a user to accumulate such an amount just by using the faucet.
You are right! It takes a very long time on freebitco.in to reach 30k sats if you don't have any referrals, don't gamble or bet (as those could give you extra RP as it you have enough, you can convert them to BTC). I always struggle to gain referrals so faucets are not for me anymore.
I actually do not think there is still any functioning bitcoin Faucet besides freebitco, if any still exists out there, it will likely be a Trojan fest platform where if you visit, the site will install trogan and other harmful viruses into your device system through their ads that they purposely make to cover important information, and when you try to click cancel to close the ad, it's as if you clicked the ad itself to open.
Businesses today have better ideas on how to get users, and not through building a bitcoin Faucet, because cryptocurrency users in their right sense won't try to accumulate bitcoin Sats through Faucet, it's something one may do until he or she passes on and still, he or she won't reach the minimum withdrawal threshold.
So, when it comes to a working bitcoin Faucet, I personally still see and consider freebitco as the one and only we have at the moment, there used to be alot of faucets in the past, but not anymore.
