On November 29, 2022, I sold 1 vertical call spread on Ethereum cryptocurrency with an expiry set for tomorrow November 30, 2022. For this trade, I got a premium of 0.00295 / ETH / $3.57 at the time of writing Selling crypto options is pretty much the same as selling stock options, except they might be settled in crypto, require less capital, are settled European style (cannot be assigned before the expiry),
