everybody wants in on this huge market. this is not strange that financial institutes like banks are interested in bitcoin. and since they can not take control of bitcoin (it is too late) they are trying to get in on the technology by only using the blockchain technology.
but in the end all they are going to achieve is an AltCoin
Well yes the technology behind the blockchain is innovating and it is brought to you by bitcoin.
Banks may try to copy it but bitcoin really got a big head start. Having a new coin competing with bitcoin is an adoption.
However i doubt it will be succesful.
