Crypto Mining is central to the overall operation and function of a blockchain.
Without mining, no new coins would be released into circulation, and more importantly, the transaction occurring on a blockchain wouldn't be verified, confirmed, and added to the blockchain.
Mining, while it incentivizes miners to contribute to the vast, decentralized network of computers, more importantly, secures the entire blockchain.
Mining executes the record-keeping process that the distributed ledger technology is designed for.
The more computing hash power a miner has, the faster it can answer the lottery and earn a reward.
But will the rewards be enough in the future as the difficulty of mining increases?
