Opened 0329 BTC 65000 options straddle strategy, hold until the last moment, exercise the option to close the position.
I made a big loss for the first time since I entered the currency circle. I lost 1/3 of my invested capital. The main loss was due to too much slippage. The handling fee was not bad and the exercise fee was lower than the handling fee.
It’s not cost-effective to drive a long straddle because the time discount is too big
