Doing faucets are worthwhile if you can somehow get a lot of referrals.
One guy who uses my faucet, according to my database, he makes 0.001 or more a day without doing anything, he makes all that money off referrals. So if you can get a lot of referrals, using a faucet is worthwhile.
I know I know, but its not just that.
If for some reason you can't get referrals (because the faucet is old and people already are referrals to other guys), then you can still earn alot.
Look you open each faucet link 1 after another, it doesnt take more than 15 seconds to fill a captcha, and use faucets that pay hourly. By the time you finish the list, the cooldown of the 1st faucet is already over and you can repeat it.
I calculated that with that precision, you can easily gain about 100$/month only on this bitcoin price.If the bitcoin price rises, that can be 1000$/month!!!
And that is a good salary in 2nd and 3rd world countries , so definitely people should do faucets.
And they should do it now, because until the price goes back to 1000$/BTC you can hoard more bitcoins, and then when it reaches that price you can be rich, relative to your country's economy level.
