Ever since Bitcoin was introduced back in 2009, this cryptocurrency has had the distinction of being something you could mine with your computer—putting your hardware to use helping the blockchain technology Bitcoin is based on record and verify transactions by solving complex math problems.
As a reward, you’d get Bitcoins. But it was a very slow process for a single PC, and the necessary component for success was a high-end GPU. One GPU brought to bear on Bitcoin could take years to find one coin, so miners started building massive farms akin to data centers but without enclosures. The result was that Bitcoin farms bought up all the GPUs, causing severe shortages and infuriating gamers.
