I am part of the core team, so let me take a minute to respond to some of your points. Apologies for not responding here sooner or being that active on BTT but this is not the current teams ANN thread (Looking to possibly create one with the launch of the updated blockchain consensus) Still to be determined.

1.) Additional exchanges will be pursued after the release of the new consensus mechanism. Honestly, there are very few exchanges worth the listing fees that are being requested (even smaller exchanges) due to the amount of wash trading that occurs. That said, we do have a list of exchanges we will be targeting in the future. HitBTC currently is not one of them. They are one of the worst in terms of wash trade volume.

2, 3.) Yobit fixed our wallets recently too. However, they have been unresponsive to our support requests since the wallet was placed back into maintenance (approx 3 months ago). FYI they have the lastest version of the wallet. There are no issues

4.) It is unfortunate Coinexchange is closing. However, that is a business decision that they are making. It is not related to us. Im sure it wont be the last exchange that closes its doors.

5.) The market has been bleak for all of crypto.

6.) Impossible that you heard POS was in progress in 2017. The development team currently in place did not come into the picture until February of 2018.
