"I see you received total of 701 steem transferred and you sent total of 20 steem to like resteem bots few weeks ago so that is why you only have 680 steem in your pocket."

You are missing the point! Certainly I would agree that 700 Steem minus 20 Steem would account for me having only 680 Steem left if that were the only issue. But what you are missing in your calculation is the fact that my 1000+ upvotes paid me a net of NOTHING, whereas by my estimate, they were worth a minimum of $30.

But in any event, how can you explain the fact that I received virtually NOTHING for over 1000 upvotes, posts, comments, and replies?

"I agree with you that there is a glitch on the internal rate to calculate the account value. It is nice to look at third party services like steemworld to find out the real value using the market price."

I think it is quite obvious that there are glitches in far more than your account valuation process.
