Earnity’s Dan Schatt and Domenic Carosa believe two developments have contributed to the current evolution and composition. The first is the creation of bitcoin mining devices. Because bitcoin mining is a lot of guesswork, getting the correct answer before others has almost entirely to do with how fast your computer generates hashes.
Computers with standard CPUs dominated bitcoin mining in the early days. But, as the mining difficulty increased over time, it became more challenging to discover transactions on the network. According to some estimates, finding a valid block at the early 2015 difficulty level would have taken a few thousand years on average” using CPUs. Eventually, miners discovered that graphics cards (GPUs) were more effective and faster at mining over time. Unfortunately, they used tons of power for individual hardware systems that may be unnecessary for cryptocurrency mining.
Miners now use mining machines known as ASIC miners with specialized chips to mine faster and more efficiently. Bitcoin mining is so competitive that miners can profitably use only the most advanced ASICs. Energy consumption costs exceeded the revenue generated using desktop computers, GPUs, or older ASIC models. Subsequently, even if you have the most recent model, one computer is rarely enough to compete with mining pools.
Earnity’s industry experts, Domenic Carosa and Dan Schatt, believe Bitcoin forks have also impacted the composition of the bitcoin miner network. They are splits in the transaction chain caused by differing user perspectives on transaction history. These splits result in new versions of Bitcoin currency and are a natural result of the blockchain system’s structure, which operates without a central authority. Additionally, these forks provide different purchasing options for cryptocurrency.
Individual miners using regular computers played a role in the early days of the cryptocurrency, but large mining companies running mining pools spread across many geographies now dominate the bitcoin mining ecosystem. Bitcoin mining is also controversial because it consumes enormous amounts of energy. Consequently, with increased awareness of climate change, several miners have relocated operations to areas where renewable energy sources generate electricity.
