It has the same coin issuance rate as Zcash and is only a few months behind.  I think the best way to judge its potential value is to see it's on 0.7% the price of Zcash and has acquired a major Zcash developer, he's about the only one who is not an employee of Zcash's 20% dev mining fees.  It was 1.1% the price of Zcash 45 days ago so it fell a lot faster then ZEC as bitcoin rose.  So I shifted a lot of ZEC to HUSH.   Then ZEC kept falling and I shifted BTC to ZEC.  Right after I bought BCH at 0.1 and sold at 0.2...kind of good luck lately.....if HUSH returns back to my avg buy in.
