Bitcoin mining is easier to understand when you stop thinking of it as "making coins" and start thinking of it as network security.

Miners verify transactions, bundle them into blocks, and compete in a proof-of-work race to add the next block to Bitcoin's public Ledger. That competition is intentionally expensive. It makes fraud and double-spending far harder.

Bitcoin also adjusts the mining difficulty roughly every 2 weeks, so blocks arrive at about 10-minute intervals, regardless of how much mining power is online.

The cost is the defence. That is why changing old transactions is so hard. An attacker would need to redo the work and catch up with the honest network.

Does Bitcoin mining make more sense once you see it as a security model rather than just an energy story?
