Because you will be able to earn fees validating the blockchain activity, one could speculate that If that activity included Big exchanges (ETHfinex?!), or big fast food chains(mcdonalds), or payment services like alipay.. etc. That the activity would be huge. So you could assume if omisego at some point is validating billions of tx's on the blockchain on a daily basis and that you the holder staking your omisego would collect a nice reward.

I am hodling long term(years) and buying more over time.
