It will be too good if bank using blockchain because cryptocurrency usually disrupt bank system.
and if the bank use blockchain, the blockchain network may congested due the crowded network.
I think banks getting into blockchain or even using them is a pretty bold move, there has been rumors and
speculations between banks and cryptocurrency which people are well aware of. But still I believe it's a fresh
and productive adjustment if the term suites it, an upgrade that if managed and carefully executed efficiently
well would and could definitely bring in a success none like the other. It might even be rewarding and this
could boost banks reputation all throughout over the world. Although issues and concerns about transaction
and service fees will come to light, but still it's a little fee we pay for the quality and security that banks can
thoroughly deliver. I wouldn't mind it as long as cryptocurrency does well in the market.
