Steem estimated value keeps declining

increased supply. the price falls. market rules

The price of steem is declining over the past couple of days relative to USD, BTC, etc.

As it says in the wallet, the "estimated value" is based on the 7-day trading average of SBD (the Steem currency). You can see how it's doing here:

Part of it could be that the market cap is going down. Another part of it could be that the market cap is going down precisely because new sign ups seem to be frozen. There is no growth going on unless I'm wrong about the sign ups.

Thanks for the help my fellow steemers!

With sign ups on hold, there are people locking up steem.

Why are signups on hold though? Is something seriously wrong?

They are revamping the security which means they to change the process of how new users signup.
