Citi and Nasdaq had a blockchain project that is already up and live. Can't find a link, but I swear I've watched it in a blockchain event in youtube.
However, these are small scale use. Afaik, no blockchain is able to scale to creditcard usage yet (and stay secure at the same time). Ethereum Foundation is working hard on this. Not sure about Bitcoin. So as far as ETH goes, there's basis on it's price growth.
Can you mention one of them? And his/her knowledgable argument.
