You do not necessarily need faucets but they are good for starting with Bitcoin.
And it is. Do it for the fun or for the curiosity. But even after hours, you will end with just some cents. It probably won't pay the electricity costs of maintaining your computer powered on to do this.
There is no fun or anything to learn typing capatcha's and getting dust in a wallet. They would be so much better of even buying 5 dollars of BTC if they are wanting to play around with just a little.
The faucet rate is crazy low, and a waste of time. You could do a much better time learning a service or something else instead of using faucets.
You have no idea what you're talking about.
