Staking Cardano earns a profit in terms of ADA rewards for the tokens that are delegated to a staking pool. That way, you get your tokens to work for you instead of just letting them lay idle.
The Cardano Foundation is launching a new staking pool. It is called Sygnum Pool - a high reward staking system that employs a smart risk management approach together with Sygnum Bank.
The pool is also a main node with an external public address, so other Cardano users may assign to it and receive increased APY.
