Why to use faucets?

Now, I remember having some time to waste about 5 years ago and playing with bitcoin faucets. Made about 100000 satoshis, not much, but still some time went into that activity of visiting all kind of sites filled with spam.

Then I got more interesting things to do and forgot about the faucets. And the satoshis which were less than a dollar in value. Now with the bitcoin at $7400 they worth about 7 dollars. Not enough to get rich, but if I would have kept on milking the faucets for 5 years there would have been some dineros.

And now the bet is to try and use faucets to coins that might be valuable in the future, like Groestlcoin for example.

What are your thoughts about faucets?
