Hello and thanks for commenting. You are absolutely correct - this problem only occurs during peak usage and your usage will decrease as posts/comments get older than 7 days. If you look at some of my other replies you'll see that I worked out how much bandwidth a post or comment uses:

After I'd posted this blog I carried on with my investigation and I discovered something: I recorded my usage before and after, and the difference was 3,259 bytes. Then I pasted the post into Word and it showed me the number of characters (without spaces) was 3,259!!! So each character in your post uses 1 bit of bandwidth.

I know what you mean about being sad to not comment and interact with people, and therein lies the answer to your remark how to best earn on Steemit, because it is exactly the action of commenting and interacting that will enable you to earn, and make some great friends and supporters too! Just have patience and enjoy yourself, and try post good quality material, that's my approach.

I wish you all the best and hope to chat again!
