BTC'S SECURITY MODEL IS BROKEN?

Summary from the TLDR Crypto newsletter

Bitcoin's security model is unsustainable because it requires the cryptocurrency's value to double every four years or necessitate very high transaction fees, both of which are impractical. The reduction in the block reward every halving severely lowers miner incentives, leading to decreased security and potential vulnerability to attacks. Significant changes, such as increasing Bitcoin's supply or accepting extremely high fees, are needed.
