What? what do you mean by adding more speed to the network? do you know what a future contracts provider is? i guess that you dont.
btc rising without CME , CME may add more speed to bitcoin price and can see daily price update.
They are not going to add speed to the network, if you are trying to mean "price" the it is not going to happen too. because they are not going to buy bitcoin directly.
The ones who are going to buy bitcoin are the ones who invest through those futures, if the do not buy those future contracts, then they are not buying bitcoin, which is the same as nothing.
