What Is the Economic Incentive for Honest Miners to Maintain a High Hash Rate?

Honest miners are primarily incentivized by the block reward (newly minted coins) and transaction fees. A higher hash rate increases their chance of mining the next block and receiving this reward.

Furthermore, by collectively maintaining a high hash rate, they secure the network, which sustains the coin's value. If the coin's value drops due to an attack, the profitability of mining also falls, creating a self-reinforcing economic incentive to maintain security.
