For those who don't know, Terra suffered a catastrophic event this week which sent shockwaves throughout the crypto world. I got cliff's notes on what the public thinks happened.
A huge player (some think Citadel) borrowed 100k BTC, taking a short position on it and used those tokens to buy UST (an algorithmic stable coin* on Terra). This player then started selling off all of the UST rapidly. This started a run on investors selling off their UST. To prevent UST from dropping in price (because you can't let a stable coin get down to $0.98, much less $0.60), Terra's fund started selling off all the bitcoin it held to buy UST and keep the price up. Terra held so much bitcoin that selling it off majorly affected the price of BTC. Whomever took the short position on BTC could cash out now and win big, but word is they have not yet done that. Luna has lost tens of billions in assets and I've heard rumors of suicides among investors.
Takeaways:
- Terra broke a general rule of thumb that a platform shouldn't hold huge amounts of non-native tokens on their platform. This scheme doesn't work if they aren't holding huge sums of BTC.
- Probably wise to stay away from algorithmic stable coins.
- Watch out for staking funds that promise too much. In order to get people on their platform, Luna was offering unrealistic returns for staking (20%) on their Anchor protocol, which made them vulnerable.
- I've mentioned this before, but in theory, because it is also proof of stake, you could attack Ethereum like this, but it would take a major government to have the battle chest to execute it. Citadel has nowhere near the funds to try to pull something like this off on their network. This is one of many reasons I've been bullish on ETH.
*Not to be confused with real stable coins, like USDC, which are actually backed by cash.
