Those people saying that bitcoin is dying or that is a failure cannot really say anything else, why would they do it? Do you think they are going to praise bitcoin when their jobs are at stake? The banking industry tought that it was immune to being made obsolete by the advancements of technology and now they are discovering that they are like any other industry and given enough time there is a chance they are replaced by bitcoin or a future generation of superior cryptocurrencies.
Yes, they are mad about this possibility. But don't underestimate their strategical and machiavellian capacity to turn the tables at their favour again. They already know Blockchain isn't their enemy, Bitcoin is. They will try to use Blockchain, but excluding Bitcoin. They will sell an idea that the Crypto-Currencies they advice people to use (the currencies that are under their influence) are superior to Bitcoin in all aspects.
They will change the faces, the labels, but the content will continue being the same...
