Review n: I reduced my position because I saw a pullback. I only have two call options for BTC and ETH left in my hand. Other derivative products have been cleared. Then there was an unexpected surge, and in several groups, my friends took the opportunity to mock me crazily for looking in the wrong direction and affecting my mentality (I usually like to scold them, but finally got the chance to scold me) At this point, you are completely afraid to contract short because you cannot see where ETH is going. BTC also oscillates frequently between residential areas. Just add two BTC doomsday put options. Form a cross variety cross option portfolio. Compared to being bullish on ETH and bearish on BTC, being bullish on ETH/BTC's volatility. This strategy can only be implemented in the cryptocurrency industry. Already out of the scope of option books The empty position filled in eth 2862 is somewhat speculative in nature. I am doing delta hedging for call options in my hand, and it has already been flat this morning.
