Defi liquidity mining is not a cryptocurrency market transaction. The volatility of the cryptocurrency market depends on many factors such as market supply and demand, investor sentiment, etc. This is why everyone chooses USDT to participate in Defi mining pools. USDT is usually pegged to fiat currencies such as the US dollar, so participating in Defi mining pools will not cause any profit losses due to the "bull market" and "bear market" of the crypto market.
