Blockchain is the First online wallet, and it got a lot trusted from all "new" bitcoin users.
I think blockchain will keep improving and give their best service to others.
Also a lot people still using blockchain to check some transaction Tx id.
EDIT after 5 minutes: I'm sorry if blockchain here is stand for all transactions in bitcoin, and not about the online wallet.
Yes, OP is talking about the actual blockchain, not blockchain.info
To sum this OP, banks are just trying to cope with the fact that they will get eventually deprecated by Bitcoin, so they are selling this "blockchain technology" propaganda to keep living longer. But the fact is, a blockchain without a decentralized token like Bitcoin, it's just a more fancy excel spreadsheet, something boring and unexciting. The real progress will be on a decentralized blockchain and Bitcoin's one is the king.
