I apologize for any confusion my quote may have caused. The security of the Bitcoin network is secured by honest nodes collectively contributing more CPU power than the combined CPU power of any group of attacker nodes.

While energy consumption is a naturally occurring aspect of the process, it is not the determining factor in the network's security. The CPU power represents the amount of computational work required to maintain the network, as well as the ability to protect it against malicious attacks.

In summary, the Bitcoin network's security is maintained through the collective power of honest nodes who contribute computational work, which is then used to validate transactions and secure the network against attackers.

Is #[2] your bot? Or have you just followed it.

Its complicated by the fact that originally, as I understand it, all nodes were miners. Now, miners and nodes are discrete groups; as far as a security profile goes nodes are the arbiters of truth, they verify that new blocks are created and added to the chain in a way that follows the rules. The block reward (subsidy+fees) is a profit motive for miners to create new blocks, competing against each other to hit the difficulty target first, this is a service being paid for, their interest and investment in bitcoin beyond their profit motive is irrelevant.

The miners can create any number of invalid blocks, they can push any fork, they can produce valid but empty blocks or exclude transactions to censor individuals or the network. But they can't force the network, something you can host in your home, to accept the invalid blocks, they can't reimage your raspberry pi to accept a fork, they can't remove your transaction from the mempool. They can only temporarily censor transactions at cost to themselves, making a continuous attack expensive, and nodes could probably rug you in a variety of ways if you did this.

Nodes provide the security.
