I have recently had a talk to someone who is clicking faucets all the day. I said that it is not worth the time but he answered: "Getting 0.001 BTC a day from faucets might be a ridiculous low benefit of 3 cents now but if Bitcoin will reach its true potential this 0.001 BTC turns into $30 or even $300. So, I guess its more the hope than psychology.
I'm just going to negate this without calculating anything. You can earn a lot (more) cash if you spend the same time doing an actual job!
You don't need to have some special skills. Jobs that include something simple as a shovel or lawn mower will earn you more than faucets (as a free bonus they burn calories too!).
Yes. Something about free money makes us lose focus on what's actually going on. We all want a get rich quick scheme but they are usually too good to be true. When you do the calculations and convert to USD you will see how little you are actually making with faucets. But still we do it - probably has something to do with human psychology and maybe related to gambling.
