Liquidity mining on Tegro lets you earn gems by placing open orders. The longer your order stays active, the more gems you collect per minute. You can maximize your gems collection by placing larger orders or by pricing your orders closer to the market’s mid-price. For instance, the mid-price of the WETH USDC trading pair is $3000 and two traders - Alice places a $50 buy order for WETH at $2990, while Bob places a $75 buy order at $2995. Since Bobʼs order is larger and closer to the mid-price, he earns more gems than Alice.
