Did someone know what is this on my cryptsy account? :
Description: BTC Balance Rebate for 2015-02-27
(receive some satoshi and usd cents..?)
Yes, they pay "interest" on BTC and USD balances. Haven't bothered to see how much this is as I have no plans to keep balances on exchange

Oh! Thanks, nobody like to leave btc in exchange.
So the question is : how much is receiving Otoh? (Or maybe the BTC tight in orders are not eligible for "interest"?)
