I’m new here as well, so I don’t know for sure, but from what I understand, the account value has gone down recently because Steem’s value has gone down recently. It went up to like $6 or something before I joined, and my account value was at $2.40 i think, but Steem’s value has since dropped to like around $2.50 I think, so account values have dropped accordingly. If Steem rises in value, you’ll see your account go up again.
