Atlas Stake Pool is currently saturated. Once a pool passes the saturation point (~67.97 mill ADA), the ADA rewards payouts will begin to decrease for every delegator in the pool. Please keep a look out for this metric and consider an alternate Cardano community pool.
If you are primarily interested in the Sundae token distribution via the SundaeSwap ISO there are still unsaturated pools available. You can reference the saturation levels on this page provided by CardanoPoolPeek
