Originally, Bitcoin mining was conducted on the CPU s of definition miner bitcoin computers, with more cores and greater speed resulting in more profitability. After that, the system became dominated by multi- graphics card systems, then field-programmable gate arrays FPGAs and finally application-specific integrated circuits ASICsin the attempt to find more hashes with less electrical power usage.
