With fiat question: honestly saying from the very beginning with haven't been taking into consideration this option, but after project went live we started to get a lot of requests to consider that option, so currently fiat option is under discussion, but so far I can confirm only that AIC will be currency of payment on Akaiito platform.
What comes to long term plans: first 2-4 years will go for mass adoption of platform. During that time we will as well develop Akaiito, we have a lot of additional features which will be possibly added after release.
