simple qustion needs answer

hello guys
so i was wonder whats the diffrence between the private and public hacks ?
is there any main big diffrence
and where can i buy private cheap cs go hack !

Private = Less people on it meaning it is less likely to get detected/ More expensive and harder to find
Public = A shit ton of people are using it and has potential to get detected ex: AimTux rip

public = super high chance of vac / free
private = low chance of vac / expensive

Private=Super Expensive but VIP
Public= VAC Incoming
