Without mining rewards, would miners keep the network alive with just transaction fees, or would Bitcoin collapse?
This is just another one of the many FUDs spread by scammers and Bitcoin haters, like the claim that quantum computers will destroy Bitcoin and similar stories. This FUD is pushed by fake shitcoiner scammers trying to distract you from understanding and adopting Bitcoin, so that you end up buying their pre-mined tokens and shitcoins like Ethereum.
Scammers and insiders from Ethereum love to spread this story about the security budget.
If you dive a bit deeper into this rabbit hole, you realize that the “Security Budget” problem doesn’t actually exist. Pierre Rochard explained it perfectly a few days ago on Twitter,there’s no real issue with Bitcoin’s security budget.
