1- How much of the income we have from the delegation of Sp.

There are different policies in each case, there are those who offer votes according to the SPs you delegate, there are also those who only offer as profits the healing SPs generated by the amount of the SPs, and a few other communities offer a percentage of distribution of the rewards generated

2- Is the entrance by delegation that you receive automatic from the Steemit blocking chain or does the person receiving the delegation have to make a daily or weekly manual return to his delegate?
Thank you.

The delegation itself, generates a percentage of the SP generated by the account benefited with the delegation, the percentage by healing that you get is added to the amount of the delegation, and you can see it in the wallet.

Thank you very much for your participation in our channel.
