Earn Free Bitcoin
There are several ways to earn free bitcoin without investing. Below, we cover a few.
Faucets: A bitcoin faucet rewards you with small amounts of bitcoin (called Satoshi) for completing a capcha several times a day (usually every 15-30 minutes). Faucets are able to do this because of the published advertising on their site. The more visitors they get, the more revenue they earn.
Some faucets like this one, allow you to earn from games as well.
Mining: Mining is the process of using your computer hash power to validate and create new blocks on the blockchain. Every transaction is passed to miners in blocks. Specialized hardware called ASICs are used to produce a sufficient hash power to mine bitcoin. While it is not profitable to mine at home without spending big bucks on mining equipment, there are other algorithms used by altcoins that are still fairly profitable. The best way to use your CPU and GPU power to mine and earn bitcoin is the NiceHash software, which pays for dozens of algorithms in bitcoin.
