But what happens if the number of miners goes up, and their hardware becomes much more efficient? Bitcoin used to be mined on CPUs, then GPUs and FPGAs, but ultimately miners started designing their own ASIC chips, which were vastly more powerful than these early solutions. As the hash rate goes up, so does the mining difficulty, thus ensuring equilibrium. When more hashing power is introduced into the network, the difficulty goes up and vice versa if many miners decide to pull the plug because  https://madagascar-crypto.com/
