Dear Per,
Thank you for reading my work and thank you for taking the time to contribute to the discussion.
I could not agree with you more. As it is, cryptocurrencies are already subject to substantial price manipulation and the advent of futures and/or other derivatives contracts can only fuel further speculation, which may spook other entrants into the cryptocurrency market.
Reliable price information as you rightly point out is one of the biggest issues facing the cryptocurrency market at the moment as well and until (unfortunately) regulated cryptocurrency exchanges are made more common and harmonized price information is readily available, there will always be inefficiencies between the underlying price of the commodity tracked and the futures price.
Thank you once again for your thoughts on this issue.
Yours,
Patrick
