For beginners these faucets are really good to earn some satoshis. However now due to increase in the price of bicoin, many faucets are now providing much less satoshis after claim. So if the bitcoin price goes on increasing, eventually the concept of faucets is in danger.
Very true.
But if consider as business of faucets I think it will not stop.
yes faucet will not stop by businessman and fool newbie will keep it up by spending their important time just for 100-500 satoshi every hours.
i think faucet company like you just pay only 10% of profit by users.
If you have time,even 500 Satoshi is not bad for you never no how much these 500 Satoshi will be in future.I have earned 0.001 btc with faucets when I was a newbie
