You can waste your time on faucet sites only if you don't find any other ways to earn bitcoins but if you are willing to learn then you will find many other ways of earning bitcoins which is definitely better then wasting time on faucet sites.
The time of faucets seems to have come to an end with the recent increase in fess, any time you spend in a faucet and earning from it, it is going to be wasted when you try to spend your coins and you realize the high fee you will need to pay to the miners.
How much do you even earn in a faucet? Let's say ~1000 sats per claim at most. The current fees are at 300,000 sats. You'd need about 2 weeks of non-stop claiming every hour to cover only the fees. That's rather a waste of 2 weeks.
