This is a load of bullshit.  Everyone knows there is nothing to differentiate gray and black market use cases of Bitcoin vs Ethereum.  The only thing banks have a "phobia" of is using a coin they didn't premine the entire supply of themselves because they want to pawn it off on others at a billion percent mark up.  All the R3 douchebags bought a bunch of Eth to try and accomplish this, so please, don't strain yourself too hard shilling for Goldman Sachs.  Eth distribution is likely a continuation of the existing financial structure except even worse LOL.
