Where do bitcoins come from?
With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government.

With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.

Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.

BTC miners, hard work seems to be paying off, with billions of dollars going to their coffers, Data obtained from Glasscode showed that BTC miner revenue (“Thermocap“) is now at $17.5 billion USD.

Mining is the process of adding confirmed transactions to the Bitcoin blockchain. For the resources required to mine, the blockchain network rewards BTC miners via transaction fees and subsidies. Subsidies are paid per block at a current rate of 6.25 BTC. Fees are paid per transaction. 

By mining BTC, you can earn a BTC without having to pay money for such. BTC miners collect BTC as a reward for completing “blocks” of confirmed transactions which are added to the blockchain network.
