What are Bitcoin Faucets?
If you've researched making some beer money online, you've probably heard of Bitcoin faucets. Bitcoin faucets are websites that pay you in Bitcoin when you fill in a captcha (to prove you're not a bot) and refresh the page. You generally need to hit a limit of earnings before you can withdraw.
Faucets make money from you viewing the advertisements on the page, and pay you a portion of what they earn. Many people start off thinking that it's a way to earn money to pay for small things on the side, but are they worth it?
Can you earn money from them?
The thing you need to realise is that no one is going to just give you free money, and the amount that these faucets earn from advertisements is pretty small. The best paying faucets will generally only earn you $1-$2 per week depending on how much you use them.
There are plenty of smaller faucets, but none of them are going to pay well. Their only interest is to entice people in with promises of earning, but the only people that earn a decent amount from faucets are their owners, or people who manage to convince others to use their referral links and promise them that they'll make money. If anyone's telling you that a Bitcoin faucet pays out well and then sends you a referral link, you can safely assume that it doesn't pay well, and that said person is only trying to use you so that they can get a payout themselves.
The limits that faucets set on withdrawal are to encourage you to spend more time viewing their advertisements. If you invest time in to these faucets before realising that they aren't worth it, you're more likely to keep using it so that you can reach your minimum withdrawal. It's a smart move by the faucet owners, but it is completely exploiting you and your distaste for sunk costs.
On the other hand, there are some uses for Bitcoin faucets. They're generally reasonably quick to make a few pennies, so if you need to hit a certain amount of Bitcoin to withdraw or exchange and you're only a small amount short, you can quickly use a faucet for a bit to just top up your balance and tip you over the edge. Don't forget that the price of Bitcoin can always rise, so technically your small amounts could be worth a bit more if you save them for the future. Also, if you're savvy, you can potentially set up your own faucet to earn some beer money, but don't expect to make anything serious from it. Most people have already realised that they can't make anything decent from them, and they're dying out.
TL;DR
To conclude, Bitcoin faucets are an absolute waste of time if you're trying to earn money from them. They're only worth using if you just need a tiny bit of Bitcoin to hit the minimum withdrawal for something. Faucets will cost you more in electricity usage whilst you use them than you'll receive from payouts.
You could earn much more money by using other methods instead of spending your valuable time trying to make tiny fractions of money from these faucets.
