interesting thing...
one thing is sure: Adoption will not come easily.
what I would like to know is: why a central bank should hold some cryptocurrencies?
what's the main reason?
its not about them holding bitcoin.. its about them changing their own systems so that they can sack their IT staff, sack their auditors and sack their IT security department because by using DLT(closed blockchain) the chains self secure/audit and maintain the network automatically.. thus saving them millions a year on labour they no longer need.
