Because its premined.
When you have
copy/paste github developers holding $400,000 coins to dump they keep selling as soon as there is a small buyer comes in.
HUSH is exceptional because its own devs are jumping ship abandoning and going to a new premined fork BTCH scam coin. That's called
jump-ship copy/paste premine developer team.
Its still better than 100% premined ICO for Vitaliks pocket.
