I bought 31.000 FRI yesterday and already earned a little over 120 FRI in fees worth ~$25.
That's 0,4% "interest" in one day and people just now start to discover this, so this can only grow.
I'm purely curious and this is an honestly puzzled question: wasn't your theory a little bit backward?
They put a flat 1% fee on every transaction and divide them amongst holders proportionally in staking model. So, if someone keeps holding, let's say, 31,000 FRI and the numbers of holders grow as the project gain popularity and people start discovering, it can only shrink perpendicularly with the growth of of token holders, because the sum of stakes will grow too.
I agree, that sounded backward.
What I meant with "this can only grow" is; we are still in the first week of this project and price is still low.
Fees are all based on transactions. Listing new pairs against FRI and integrating it on other platforms can increase those transactions by a lot.
It's all "in the works" so no need to hurry.
