the faucets give only a very small amount of coins. look for airdrops. i can recommend the Ethereum Dark Airdrop. Very easy to handle and the price is going up. free money.
I'm specifically looking for ones that give a large amount of a new coin or a coin that isn't worth much. 1000 of a coin may only be worth $0.01 but if that price doubles, then every previous claim would have been worth $0.02.
I dont think that there are some, which would give you a good profit. Faucets are useless really, it is better to look up for some bounty campaigns on this forum.
