Whether Cardano, Solana, or any other crypto, several factors impact staking profitability. For example, the performance of the pool, its size, and the cost of running it are some of the factors that can impact returns. On Cardano, a fixed cost of 340 ADA applies to a stake pool as a whole. Therefore, participants in the pool bear a portion of this cost. Also, pool operators charge a fee as compensation for their service.
