You can earn cryptocurrency through mining without having to make any investments.
Bitcoin is awarded to Bitcoin miners for validating transactions.
The first miner to figure out a tricky hashing puzzle receives mining rewards. The likelihood that a participant will come up with the solution depends on how much of the total mining power in the network.
To set up a mining machine, you will need either a GPU (graphics processing unit) or an ASIC (application-specific integrated circuit).
Bitcoin is a sovereign digital currency. It is not directly linked to any real-world currency and it is not controlled by any government. However, people can use it to buy real-world goods at major retailers like Overstock.com or Expedia.
The blockchain is the foundation of all mining. A "block" is a group of approved transactions.
This requires immense computational and electrical power.
