Nischal Shetty, CEO of India-based crypto exchange WazirX, believes that the primary intention behind liquidity farming from the very start was to simply attract users, giving them an opportunity to try out DEXs and understand how to use them: “So despite the initial drop in liquidity when the mining rewards stop, I don’t think there will really be a decline in usage because the people who want to buy/sell crypto via a DEX, and have discovered the DEX, will stay back.”
