Bitcoin's role as part of central bank reserves

Central banks require a clearing settlement device among currencies.  Gold has served that function historically, however, has issues.  Namely: dollar-settled derivatives, requires a vault, and is difficult to transport.

Bitcoin solves these problems.

It is my suggestion that some focus and energy be placed in communicating the advantages of Bitcoin to the various central banks around the world.  This requires trading desks and exchanges to provide liquidity.  The German central bank comes to mind.
