Bitcoin suffered a dramatic sell-off on May 10, 2022, plunging below the \$31,000 mark for the first time since July 2021 as the collapse of Terra’s algorithmic stablecoin UST sent shockwaves through the entire cryptocurrency market.
TL;DR
- Bitcoin dropped to \$31,022, losing roughly 18% over the previous seven days
- Terra’s UST stablecoin lost its dollar peg, falling to approximately \$0.80
- LUNA token crashed 45% in 24 hours and nearly 79% over the week
- Luna Foundation Guard deployed billions in Bitcoin reserves attempting to defend the peg
- Total crypto market cap shed hundreds of billions amid cascading liquidations
The crisis centered on TerraUSD (UST), an algorithmic stablecoin designed to maintain a 1:1 peg with the US dollar through a complex arbitrage mechanism tied to its sister token LUNA. On May 10, UST traded as low as \$0.7999, a devastating break from its intended parity that triggered a full-blown panic across digital asset markets.
According to CoinMarketCap data, Bitcoin’s price stood at approximately \$31,022 on May 10, representing a steep decline from the \$40,000 range it had traded at just weeks earlier. The sell-off was accelerated by massive forced liquidations in the derivatives market, as leveraged long positions were wiped out in rapid succession.
The Terra Death Spiral Begins
The mechanism behind UST’s collapse was brutal in its simplicity. UST maintained its dollar peg through an algorithmic relationship with LUNA — users could always exchange 1 UST for \$1 worth of LUNA. When confidence in UST began to waver, a wave of selling pushed UST below \$1. Holders redeemed UST for LUNA, which they then sold on the open market. This created an ever-expanding supply of LUNA, driving its price down further and undermining confidence in the entire system.
LUNA’s price plummeted to \$17.52 on May 10, a staggering 45% decline in just 24 hours and a nearly 79% drop over the preceding week. The token had been worth over \$100 just a month earlier, making this one of the most spectacular collapses in cryptocurrency history.
Luna Foundation Guard’s Bitcoin Deployment
In a desperate bid to restore the UST peg, the Luna Foundation Guard (LFG) — a non-profit organization established by Terraform Labs founder Do Kwon — began deploying its massive Bitcoin reserves. The LFG had accumulated approximately 80,000 BTC (worth roughly \$3 billion at the time) specifically for the purpose of defending UST during periods of market stress.
The LFG’s Bitcoin sales added additional downward pressure on BTC prices, creating a feedback loop that exacerbated the broader market sell-off. As the foundation sold Bitcoin to prop up UST, BTC itself declined further, reducing the value of the remaining reserves and undermining the defense strategy.
Broad Market Contagion
The contagion from Terra’s meltdown spread rapidly across the crypto market. Ethereum traded at approximately \$2,343, down nearly 16% over the week. Solana fell to \$66.77, representing a 22% weekly decline. BNB dropped to \$319, and virtually every major altcoin posted double-digit losses.
The total cryptocurrency market capitalization contracted sharply, with the combined value of all digital assets falling below \$1.3 trillion. Just months earlier, the market had been valued at over \$2 trillion, meaning approximately \$700 billion in value had been erased.
Forced Liquidations Compound the Sell-Off
The speed and severity of the decline was amplified by cascading liquidations in the leveraged derivatives market. As prices fell, over-leveraged long positions were forcibly closed by exchanges, generating additional selling pressure that pushed prices down further. Data from various analytics platforms indicated that hundreds of millions of dollars in long positions were liquidated within a 24-hour period.
This liquidation cascade created a classic feedback loop: falling prices triggered margin calls and forced sales, which drove prices even lower, triggering additional liquidations. For traders using high leverage, the move was devastating.
Why This Matters
The Terra UST collapse of May 2022 represents a watershed moment for the cryptocurrency industry. It demonstrated the fundamental fragility of algorithmic stablecoins — tokens that rely on market incentives and arbitrage rather than actual dollar reserves to maintain their peg. The event would ultimately lead to increased regulatory scrutiny of stablecoins, billions in losses for retail and institutional investors, and a fundamental reassessment of risk across DeFi protocols.
For Bitcoin, the Terra crisis underscored the interconnectedness of the crypto ecosystem. Even though BTC operates on fundamentally different principles than algorithmic stablecoins, the contagion effect proved that no digital asset is immune from systemic risk within the broader market.

BTC at $31K and LUNA down 79% in a week. the contagion was spreading faster than anyone could exit. brutal
BTC at $31K and the contagion had barely started. three arrows, celsius, voyager all came after. this was just the beginning of a brutal summer
LFG deploying billions in BTC reserves trying to defend UST at $0.80. all that achieved was selling BTC at the bottom
LFG sold billions in BTC trying to defend a peg that was mathematically doomed. they made the BTC dump worse for literally zero gain
LFG selling billions in BTC reserves to defend a mathematically doomed peg just dumped on the market for zero benefit. they made the BTC crash worse trying to save something unsalvageable
the arbitrage mechanism was designed to expand LUNA supply when UST dipped below $1. so more LUNA meant more selling pressure which meant lower LUNA which meant more minting. textbook death spiral
^ this. every algo stablecoin has this same flaw baked in. you cannot create value from nothing and pretend a mint-burn mechanism fixes it
UST at $0.80 was the point of no return. every algo stablecoin has the same death spiral baked in. you cannot mint your way out of a confidence crisis
