Many people hear about Bitcoin mining and wonder what it is exactly and what is involved to get started. Cryptocurrency mining can be a complex process that takes time to master. However, it can also be incredibly rewarding and lucrative. By using BT-Miners, we can help walk you through getting started with various forms of crypto mining.

You may understand that you can purchase cryptocurrency such as Bitcoin, Ethereum, Litecoin, Kadena, Ripple, etc. on a marketplace. The main benefit of "mining" is being able to earn this cryptocurrency without having to spend money directly to get it. A Crypto Miner, often called a Mining Rig in the industry, is a piece of sophisticated computer hardware that performs certain tasks. For each completed task, you are compensated in crypto which can be saved, spent, or converted to other assets. The components of a typical miner are similar to that of high-speed computer. However, unlike your basic home computer, Miners are specialized equipment designed to perform certain mining-specific tasks.

The ways you can earn this currency differ; one way, for example, is by validating crypto transactions on a Blockchain network. But put simply—a miner gets rewarded in crypto by completing certain types of work. Besides when maintenance is needed, there is little actual work that you have to do for your Miner to successfully mine. No hard hats or pick axe required!

The average hash rate gives a better indication of overall performance than the real-time hash rate. The 24-hour average hash rate of a miner running continuously should be in the range of plus or minus 10% of  the tagged hash rate. If the 24-hour average hash rate is not within this range, please contact our after-sales service for assistance.
