$Advanced Micro Devices (AMD.US)$ All in... AMD will rise above 140 again this week.

Although earned a total of USD500+ after two days of trading.
Earned USD740+ on the first day of trading.
Closed at a loss of USD210+ on the second trading day, although I think I can earn all the premium before the new government takes office, because most are digital currency enthusiasts.
Although this is a Bitcoin concept stock, the price fluctuations do not entirely depend on the rise in Bitcoin, there is also a serious concern about the premium on this stock. The Fair Value is around 50%. There are also issues with the two ETFs tracking MSTR, the tracking is inaccurate because of high uncertainty and contract supply exceeds demand.
While the price of Bitcoin surged, MSTR's stock price continued to decline, which made me a bit nervous. In the end, I chose not to trade options on this stock temporarily and switched to a more stable Bitcoin ETF. $iShares Bitcoin Trust (IBIT.US)$ $ARK 21Shares Bitcoin ETF (ARKB.US)$ Continue to trade investments related to Bitcoin.
This is not financial advice, just personal thoughts.

$MicroStrategy (MSTR.US)$ $MicroStrategy (MSTR.US)$ Is it true that options trading can only be done during trading hours, and can options only be sold during trading hours on the expiration day? Will they be automatically exercised or abandoned after the deadline?
