BITCOIN Future Contracts

[hwarico]

as CME Groupe listed the Bitcoin as future contract to be trades , shall it be positive for the real markets or negative ??
 
for my point of view the future contract may decrease the real markets volume , also the short selling may be more negative for the prices ......
