Here is the launch profile. http://i.imgur.com/D9BdO86.png

Launches to GTO need to be going a lot faster (7.7 km/s for ISS, vs 9.88 km/s for GTO). The Falcon 9 uses up enough fuel that it cannot execute the "boostback" burn listed in the image.

Instead it continues on in a parabolic arc until it hits the atmosphere to slow down, firing the rocket at the last minute to stop over the drone ship.

What they fail to understand is banks WANT centralized authentication and authority. Its how the banks exercise power over another. The bigger bank tells the smaller banks what to do.

Even if blockchains could perform all the tasks they claim to, it basically takes the authority and control out of the hands of the big bank and evens out the control so no one entity can corrupt it. It might be best for the system and the people, but the big banks won't go for it.
