Whaleshares does have a reward pool but it goes directly to you if you claim it each day. You can then decide if you want to use it for tips, keep it in your account as stake or a mixture of both. I don't know the percentages but for 221000 WLS approx stake I get approx 154 WLS per day. It changes each day, depending on how much is staked but that is the amount the last few days. It used to be closer to 200 per day but a lot of people were buying the tokens and staking them instead of keeping them liquid.
