Certain exchanges in finance: whether legacy markets like FOREX and stocks, or cryptocurrency markets like bitcoin and litecoin, offer a fee structure called the maker/taker model. It's pretty simple how it works:
Maker order is when you create a bid or ask and put your order into the orderbook, waiting to be filled by a counterparty.
Taker order is when you fill an existing order that is in the orderbook, removing liquidity from the market.
With the goal of having higher volume, some exchanges will have 0% fees (as the Chinese bitcoin spot exchanges are famous for) or they will even have negative fees for maker orders, also known as a rebate, which actually compensates traders who provide liquidity to the market by filling the orderbook.
The maker/taker fee model in bitcoin exchanges is a great way to get traders to actively pack the orderbook, which tightens the spreads and benefits everyone.
