Big Banks are researching the usage of private Block Chains, and not Ethereum's

[zodin]

i do not think that banks will need to study about the private block chain or to study any crypto currency like bitcoin or etherium or some one else, specially in preset position, because these currencies have yet not any bad effect of banks on on their business, may be in future they think about to develop their own block chain, but it can only be possible when the user of crypto currencies increase and most of the people use online wallet,
