This is very interesting, but I do see a slight problem in that by making it impossible to spend the bitcoins during the time of the contract, it reduces the contract makers cashflow. This would, theoretically ensure that there was a reduction in the total number of coins in potential circulation and possibly create some form of inflation.
I know this is mostly theoretical risk, and I love the idea of seeing a new market for bitcoins, but I do wonder if the advantage is limited?
Have I misunderstood a crucial element of the plan? ;-)
you are correct in your assertion that during the duration of the options contract the underlying asset is unspendable. you can solve this cashflow problem by instead creating an option on a
bond derived from the said asset. This of course introduces the dimension of RISK and DEFAULT. Naturally the option is going to be worth more if the credit risk associated with that bond is more attractive. When this technology is ready to roll, there will be a lot of opportunities for financial engineers to create systems to manage such risk.
