A user may have mistakenly bought an option worth 0.004 BTC at a price of 0.0434 BTC, resulting in a profit of nearly 4 BTC for the counterparty.
According to reports, the BTC large-scale Options Trading Volume was inactive last weekend, but there was an unusual calendar spread of buying 12OCT24-60000-C Options, with IV as high as 495%, which analysts believe was caused by user error, resulting in the counterparty gaining close to 4BTC in profit.
