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.
