Liquidity pooling on Gate.io

I recently signed up for the crypto exchange Gate.io. It has some of the altcoins that you won't find on other major exchanges. I discovered their Liquidity pool program has some very high APRs on certain pools and give rewards that can be withdrawn at anytime in the form of GT (Gate Token) which is the native token of Gate.io. The funds can be redeemed without a waiting period it appears though I have not yet tried. The APR can vary a lot from day to day based on how much volume is moving through that crypto pairing. Some days over 1000% and some days 100% for the ones I am in. It shows you the 7 day average as "7 day annualized yield".
