Mining

Cryptomining is a process where the transactions for various crypto coins become verified and then added to the blockchain ledger. We perform the exercise with the aid of super-powerful computers, which have to solve complex mathematical computations. The math problems are so hard, you cannot do them by hand. It explains why you need powerful computers.

At the time of writing this, the odds of a computer solving one of these math problems to get Bitcoin is 1 in 13 trillion. By solving these problems, the miners make the Bitcoin payments secure and trustworthy by verifying transactions.

The nodes (computers active in the network) maintain the records of the blocks for reference. Because they are immutable and unchangeable, no one can overcharge or double-charge you. Bitcoin miners do more than just mine for bitcoin. They make sure that the transactions are accurate.
