One thing to note is that while Celsius, a centralized and opaque yield platform, collapsed, not a single major DeFi protocol failed during a period of enormous stress. MakerDAO, Aave, Uniswap, Curve, Lido and Compound all had perfect 24/7 uptime with zero losses due to unrecoverable debt. This pretty clearly strengthens the case for pure and transparent DeFi, where anybody can inspect the health of the protocol or t…
