Currently, BTC's DVOL implied volatility index is at 42; selling options to earn some pocket money is still okay. The market hasn’t hit the bear market bottom yet, otherwise volatility would definitely drop below 40. So if you really want to sell call options, you might also consider buying some long-term calls at the same time. At the start of this year, the coin price surged to 93K along with the broader market, then dropped back to 89K; the baseline has actually slightly improved. I personally sold some 100K call options expiring at the end of January, and bought some 95K call options expiring at the end of March. Hoping for some action in Q1.
