According to Ai 姨 (@ai_9684xtpa), a trading error occurred where a large buy order for SPK was executed at a significantly higher rate than intended, with 1 USDT set to equal 19.931 SPK instead of the lower expected price. The trader intended to purchase $20,000 worth of SPK at the 0.05 USDT mark, but due to the manual input error, a much larger amount was transacted. This incident highlights the importance of precise order placement and risk management for SPK traders, as such errors can cause sudden price volatility and liquidity shifts in the SPK/USDT trading pair (Source: Ai 姨, Twitter, June 17, 2025).
