In the emerging global crypto economy, crypto mining is probably going to remain and even become more profitable in the upcoming years.
Miner profitability metrics are based on a handful of factors regulating difficulty and emission, which are hard-coded into the blockchain’s attributes, making it predictable to work with. While predictability does not always immediately translate into profitability, it gives a blockchain certain parameters to rely on when predicting when mining cryptocurrency will become profitable, at which price level, and at which difficulty level during the emission cycle.
Some cryptocurrencies, such as Bitcoin (BTC), go through emission cycles with events such as the halving. In Bitcoin’s case, halvings occur once every 210,000 blocks — roughly every four years — until the maximum supply of 21 million Bitcoin has been mined.
This feature, self-adjusting difficulty, provides an incentive for an individual miner to join or leave the network depending on the current Bitcoin price level. Together, these incentives create a logarithmic price regression curve, which represents a probable Bitcoin exchange rate and, therefore, predictability of profitability in the current emission cycle.
