I only found Cryptsy that has a program to pay balances holders & liquidity providers, but you have to be "verified".

How Much Will I Earn in Balance Rebates?
We pay a 2% rebate. Balance calculations include available and held for order balances. So even if all your funds are held for open orders, they are included in the calculation.
----------------------------------
A Maker makes liquidity and a Taker takes liquidity from the market.
If you are a Maker for an order, and your account is verified, then not only will you not pay any fees on that order but you will get a fee ‘rebate’ of 0.05% when a Taker completes the order.
If your account is not verified, then standard fees (0.25%) apply. Taker fees will not change and remain at 0.25%.
Do you know other exchanges with similar policies in place that respect our anonymity?
Thx a lot.
