DeFi systems are fundamentally different from currency systems like BTC. At its core, it's a financial market that operates without the constraints of smart contracts or a rules framework, making it extremely unfair. The so-called 'fair casino' needs to have limits, not be left unchecked. In the financial market game, the richer you are, the more powerful you become. Without restrictions, it becomes a paradise for crime. This is the biggest bug, and it's also why traditional markets must regulate market manipulation.
