Bad management? Greed? Stupidity? Bad planning?... What has happened (and continues to happen) with Luna can be described in many ways, but the first thing that came to mind was Bitconnect. Although the case of Luna and UST is different from what happened with Bitconnect, the result is very similar, many people bankrupt, billions of dollars that nobody finds, and a bad image (again) for cryptocurrencies. I think the point of this is that we cannot trust algorithmic stablecoins, but we can trust the ones we already know (USDT, USDC, BUSD and others).
A word of advice to everyone, USDD is also an algorithmic stablecoin and was publicly launched on May 5th (just 8 days ago). We must be careful.
