It's been 9 years. This is nothing. Think how long it took for the first known currency to be useful and ingrained into people's everyday life (created in 600 B.C. in Lydia, now Turkey), and for the concept to catch on in the rest of the world/be universally accepted.

Times have changed but the principles of what makes an accepted currency hasn't. It has to be useful and hold consistent value, which will be inevitable as every aspect of the modern world becomes virtual, including the economy.
