'Evil genius' may have caused Terra and Luna cryptocurrencies to crash in a 'death spiral'
How did the 'evil genius' plot unfold?
Nobody knows who caused the price of Terra and Luna to crash.
But many on social media are pointing the blame at the big US hedge funds, given the massive trades involved. Two firms, Citadel Securities and BlackRock, have already issued statements denying any involvement in Terra's crash.
"We don't know if the momentum was created by collusion [between hedge funds]," said Lisa Wade, the CEO of blockchain company DigitalX.
"Conspiracy theorists would say 'yes', because it's a massive trade. I mean, in all of my career, it's one of the biggest trades that I've seen," she told ABC's The Business.
"It's almost like an evil genius plot, because there are a lot of steps to it."
Ms Wade said, as part of this complex plot, the buyers appear to have purchased around $1 billion worth of UST stablecoins, while "shorting" bitcoin (which is a risky way to make money, by betting on the price of an asset falling — instead of rising).
"What they did next was they timed the market.
"So obviously we're in a really volatile risk-off stage of the market — because of everything that's been happening with the [US] Fed and the macro environment.
"They waited until a Saturday night when [trading] volumes were very low, and there were no bids.
"And then they went into a trading pool and started selling UST in massive volumes, which then triggered all of the subsequent selling in a low-volume market that broke the [US dollar] peg.
"Inside the algorithm was what our team had identified as a 'death spiral' ... the selling starts to feed on itself from the mechanics of the algorithm.
"So when the death spiral kicked in ... the algorithm started selling Bitcoin and Avalanche [another cryptocurrency], which triggers more selling.
"Luna was impacted because it's the underlying [backer] of the UST. So every time a UST [token] is bought, a Luna [token] is burnt, which means there's less tokens in supply, so the Luna price goes up.
"The reverse applies when people start selling. So every time someone sells a UST, they mint a Luna, which means there's more volume.
"And if there's no buyers and the price goes down, then it starts to feed on itself, because people start panicking and selling Luna.
"This was an exploitative trade that took advantage of the fact that markets are weaker. The perfect storm was nobody stepping up to buy the bitcoin and the UST".
'I lost all my life savings'
Unfortunately, there is a human cost to the failure of the Terra stablecoin.
A long list of suicide prevention hotlines can be seen at the top of the TerraLuna Reddit page — including Australia's LifeLine, and similar organisations from the United States, Britain, Spain, China, Sweden, and 90 other countries.
Many Reddit users have also posted stories about the consequences of losing their money from their Terra and Luna cryptocurrency investments.
"I lost all my life savings," one user wrote. "Had bought Luna at $85, not sure what to do."
"I should've cashed out when it was $100, then I would have been up $25,000," Reddit user No-Forever wrote.
"But I got greedy hoping to get more money so I can at least afford a downpayment for a house for my family. I guess no house and savings then."
What next for crypto markets?
"What upsets me is that I can look at it through a trader's lens and be clinical and analyse the trade," Ms Wade said.
"However, on the other side of that are mums and dads.
"The reason why UST was worth $US18 billion was because it was backed by a savings pool.
"That savings pool was offering 20 per cent returns. So lots of innocent people had their money saved up in their thinking they were getting risk-free deposits."
While Ms Wade said this kind of trading wasn't illegal, the ethics of it were "questionable", and she believes it will likely lead to regulation in the crypto markets being fast-tracked.
Terra's backers are currently trying to raise about $US1.5 billion to boost the value of the stablecoin, and restore its parity with the US dollar — with little success so far.
But the concern amongst anxious investors is that: if the value of a supposedly "stable" digital asset can be wiped out so easily in a few days, who else is next in the crypto firing line?
