I need to think if there is a way to leverage the Hive RCs (or Hive Power), and maybe couple this with a "stable" token. Let's say you have 1,000 Hive Power and today the price of Hive is $1, then you have 1,000 credits available on the side chain. With 1,000 credits, you can probably trigger a bunch of smart contracts that will use up your credits at 1 credit equals $1. Tomorrow, the Hive price goes down to $0.5, that only gives you 500 credits to use up on the sidechain, but your credits are still worth $1 on the sidechain (so you're not paying less or more to interact with the sidechain, you just have less ressources available). At this point, there are no bad ideas I think...
