Thanks for letting me know about these factors as it was happening with me especially Bandwidth issue was occurring severly. Thanks for highliting this important point, you made my confusions clear by saying

Note that the more SP allows you more bandwidth as a protective measure (as well) to prevent things like DDOS attacks that can cause congestion on steem. Thus, for newer steemians, a nice primary aim would be to try to accrue steem power as this gives you more bandwidth allowance and allows to you to have a say in the "reward distribution".

Means more hard work= More Sp

Let me tell my friends too about it @surpassinggoogle
