Recently I have got message from Graviex exchange about HUSH desisting. Why? Project is closed?
The project is still going strong, halving upcoming in around 46 days from now (block time will go down to 75 secs and block reward to 3.125 Hush).
New Hush version 3.5.0 which will transition Hush to a z to z only coin (no need to do anything, your hush is and will be safe), everything is ready for it but looks like graviex will not be making the change to mandatory privacy.
