To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. The Bitcoin code is written to make solving its puzzles more and more challenging over time, requiring more and more computing resources. Today, Bitcoin mining requires powerful computers and access to massive amounts of cheap electricity to be successful.
Bitcoin mining also pays less than it used to, making it even harder to recoup the rising computational and electrical costs. In the U.
