Uniswap and Curve, two popular pools for trading stablecoins, were selling millions of tethers (USDT), causing traders to show early signs of worry.

According to CoinMarketCap, USDT, which normally trades at around $1 , lost its peg with the U.S. dollar, and dropped as low $0.9968. The token traded at $0.998 recently.

USDT balances in Curve’s 3pool, which is a stablecoin exchange pool consisting of USDT USDC and DAI, reached over 72% on Thursday morning. This means traders have traded tens and millions of USDT for stablecoins USDC and dai.

Curve’s 3-pool holds more than $300 million USDT, and almost $55 each in dai and usdc.

This imbalance indicates a preference for DAI over USDC. As CoinDesk reported, such sentiments were also observed when Terra collapsed in May last year and FTX collapsed in November.

In a tweet , Tether CTO Paolo Ardoino said that traders may be trying to “capitalize” on the current sentiment in the crypto markets. This sentiment has dropped in the last 24 hours.

Ardoino told that “markets are volatile these days. It’s very easy for attackers capitalize on the general feeling.” Tether is ready to respond as usual. Let them come. “We’re willing to accept any amount.”

CORRECTION (15 June 12:17 UTC: Adds the tether loss in dollar peg to second paragraph.
