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.
There's still some margin and market for the people who will try to get into faucets. You're right, that it will still get some good referral on it by those who just got started.
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.
And when they start to see how much they need to earn for the minimum amount to withdraw, they might get discouraged about it. But I guess that they've learned the basics already after knowing that.
