With /MET and /MBT (Micro Bitcoin Futures) listing options, we need to assess if the options are tradable. Out of the two, /MBT seems to have the more tradable options since the credits on a strangle could reach $100 or more per contract, whereas /MET sees a credit of around $10 or less for the same strategy. Mind the liquidity on these options. Getting filled closer to mid-price would be necessary for these options to be considered liquid.
