Part II. 
The pool consists of 4 coins bitcoin, ether, solana and usdc. You can deposit any of these coins in the pool. Importantly your cryptocurrency is exchanged for the liquidity token FLP, which consists of the coins mentioned above. The main risk is a fall in the price of FLP along with a fall in the exchange rate of the 4 coins that make up the pool. But if the rate of coins grows, the price of your FLP grows. If you deposit 100 usdc when the bitcoin rate rises, you can get back 105 usdc + reward for providing liquidity. 
You can read more about FLP here https://docs.flash.trade/flash-trade.
Also all 4 pools are limited, for example once you reach 15 million in the first pool you can't add liquidity, you have to wait for someone to take the money out of the pool.
