The biggest issue I see is when I look on coinmarketcap.com for STEEM. There are only 2 exchanges which do any noticeable volume.
These are Bittrex and Poloniex.

The market for STEEM is open on Bittrex as I type this, the wallet works, transactions are happening.

On the other hand, on Poloniex, we keep getting the following message:

"STEEM is currently under maintenance or experiencing wallet/network issues. Deposits and withdrawals will remain disabled until a solution is found, which may require an update from the STEEM team. Any updates must be tested and audited before enabling."

It's harmful for people's trust and confidence when one exchange keeps shutting down, not giving us information about the reasons behind this and on top of that says that STEEM themselves might be to blame.

It's even more harmful, when it is the biggest exchange of STEEM doing this, with a market trading share of 48%.
