Each pool is different. Some begin paying out daily rewards and/or pool fees (accrued fees can be seen on Tribaldex*) with very small amounts of liquidity added, while others require quite a bit more. The basic idea is that you need enough of each token in the pair to add to the pool. You can't really make a mistake, because any liquidity that you add to a pool can be removed at any time, immediately. 😁 🙏 💚 ✨ 🤙
