BillieCoins are not much popular right now, so there is no buy offer on exchange. Sell offer is 40 satoshi (will take that number as example, but we know that it should be counting from buy price)
40sat*40tokens=1600sat per post
In the signature campaigns paid in Bitcoin (that have much higher liquidity) rates are much higher. (In my campaign rates are almost 20x higher)
If you want to attract bounty hunters, you should to consider much higher rates, or accept users with negative trust, that can not join to signature campaigns paid in BTC.
