Thank You for sharing this news. SBI with new crypto currency sounds good, but still there is no rule for crypto currency regulation, as per the moneycontrol news, India is preparing a law for regulation of crypto currency and it should be applied before 2018, if largest bank sector "SBI" promote it's digital currency then another revolution will be occur in economy.
SBI is among one of the top banks in the world owned by government of india, a multinational bank. If SBI adopts blockchain technology and brings it to india, i guess development in india will increase at a much faster pace.
