We always think that whenever there is a talk about blockchain, it would always be about bitcoin. Although these two are binded together but they are two different entities.
AFAIK, bitcoin was banned there since 2017. Is that correct?
Yup and probably OP is mistaken for treating bitcoin is equal to blockchain.
Now just waiting for confirmation that bitcoin (blockchain) is accepted.
And talking about the bank legalizing blockchain technology, I could sense that they're soon create their own coin/token, best example is Union Bank that adopt blockchain and soon launch their own token which is PHX.
