A brief history of bitcoin mining hardware

Bitcoin mining was once nothing more than a lucrative hobby for nerdy cryptocurrency enthusiasts. The only hardware required, in the beginning, was a simple computer. Things have changed a lot in less than 10 years.

In 2009 the first bitcoin miners used standard multi-core CPUs to produce BTC at a rate of 50 per block. If you had a couple computers lying around with decent specs you could have earned about five dollars a day. The difficulty of mining (amount of computing power necessary) was so low then it was worth it for hobbyists and crypto nerds to participate.
