Thank you everyone for your answers! I really appraciate that!
I have one more question: In the past, the best rewards were always given by BTC faucets. Is it still like that? I mean, do the altcoins faucets still give smaller prizes than the BTC faucets, or maybe something changed?

Sometimes there are better AltCoin's faucets than many BTC's faucets, sometimes they are worse and in most cases the rewards are similar in fiat.
Good faucets are hard to find, and when you find one, it doesn't last for a long time, so enjoy it maximum as possible while you can.
I'm more focused in using faucets which give us chances to earn big prizes, even if the chance is little. Like FreeBitco.in (up to $200), FreeDoge.co.in (up to $150) and I'm testing one called FreeNem.com (up to $300) too, but this one I'm not sure yet if pays. As you see, doesn't matter the currency, but the fiat prize.
I suggest you to calculate the reward in fiat of each AltCoin faucet you use.
A good idea with converting to fiat, I always compare to btc
Thanks for the advice.You wrote that you don't know if you will receive a reward. Does this mean that faucets no longer use wallets/services for micropayments?
Most faucets still pay directly to Micro Payment Systems (instantly), but some of them pay only to your wallet, so you need to claim a lot on the site until you are able to withdraw to your adress. All those faucets I mentioned offering higher prizes ($150, $200, $300) work this way. About FreeBitco.in and FreeDoge.co.in I'm sure I will receive the payment as both sites are here for years and we know its owner's legitimacy.
Only about FreeNem.com I'm not sure yet, because the site is new.
After all, most faucets with their own wallets after time have become scams.. 
You mean faucets that don't pay to Micro Payment Systems? If so, yes, many of them turn into scam on the exact moment their faucet isn't sustainable anymore. Many people avoid this kind of faucet and they aren't wrong about it. But there are exceptions.
