What is halves mean man ? and what happen after this. sr i'm newbie

Welcome to Zoin, halving means that block reward will be 50 Zoin instead of 100 which is at the current rate.
Yes. it will help this coin come back on the race. Zoin is not much interested by investors.
Dev needs more new plans to heat this project. Zoin is now quite cheap to buy it now.
Zcoin is not yet grown up highly because the lack of hardworking from Dev and commany investors has left this coin .
If this project will come back then Dev needs more new improvements for this coin to attract investors again.
