Will there be any plans or options for RSR token holders to stake them in the near future?
Reserve has currently not released any plans to stake RSR.
Arbitrage will be possible for RSR holders as soon as mainnet launches. You can read more about it here: https://reserve.org/blog/why-arbitrageurs-should-hodl.
