BTC Miner

Bitcoin mining is the process of creating new bitcoin by solving puzzles. It consists of computing systems equipped with specialized chips competing to solve mathematical puzzles. The first Bitcoin Miner (as these systems are called) to solve the puzzle is rewarded with bitcoin. The mining process also confirms transactions on the cryptocurrency's network and makes them trustworthy. 

For a short time after Bitcoin was launched, it was mined on desktop computers with regular central processing units (CPUs). But the process was extremely slow. Now the cryptocurrency is generated using large mining pools spread across many geographies. Bitcoin miners aggregate mining systems that consume massive amounts of electricity to mine the cryptocurrency. 
In regions where electricity is generated using fossil fuels, bitcoin mining is considered detrimental to the environment. As a result, many bitcoin miners have moved operations to places with renewable sources of energy to reduce Bitcoin's impact on climate change.
