Bitcoin, Ethereum, and other currencies, Mining
Crypto-currencies such as Bitcoin, Ethereum, Dash, Litecoin, Monero, and Zcash come into being by a process called mining.
Anyone can dedicate computing power to validate transactions on the blockchain. By doing so they keep it accurate and free of "false" transactions for everyone. In return they are rewarded with a set of the coins they are contributing power to.
This process is called mining, and it's a way for people to earn coins without buying them directly. Depending on the cost of the hardware, the electricity and the prices it can be a lucrative way to contribute to the network.
The more people are mining a coin, the harder it is to earn some of it and the more valuable they get. But the competition also grows.
You can buy specialized hardware, set it up and have it run yourself, or you can opt for cloud mining solutions.
