The author simultaneously claims that: 1. Crypto is a battleground where anything that can be exploited will be 2. Bitcoin is highly vulnerable to 51% attacks Something's not right here. For all the theoretical speculation about a 51% attack on Bitcoin, it's never happened, so maybe the system is working as designed. Bitcoin is relatively unchanged since 2009 by design, the author hardly mentions more modern consensus protocols like Ethereum's Proof of Stake + Slashing + LMD GHOST. Even in the most optimal scenarios the cost to attack Ethereum is astronomical.
