More and more central banks are researching the use of electronic money, they want to understand how electronic money and Blockchain technology can affect their countries.
No, they aren't even concerned on the welfare of cryptocurrencies as long as they can push their agenda and use the blockchain technology for their own services. Seeing how efficient and excellent the blockchain tech works for bitcoin, they want to incorporate it into their own systems and market it as 'cutting-edge' technology to fool people once more. Nothing special here, just a typical banker's move if you ask me.
As for the future of bitcoin and digital money, it can be integrated into a lot of FinTech services and other sectors of the society as well, but we're far from seeing it (crypto) taking over fiat anytime sooner, though it can already co-exist with it side-by-side.
