Questions before buying cheats for CS.GO

I just have 3 questions I would like to ask before buying.
Q.1 Is the cheats for CS.GO still undetected and for how long will it stay this way?
Q.2 What happens if your account will get VAC banned?
Q.3 Is 109.99CHF equal to 109.99 USA dollars?
Thank you and I hope to be buying soon.
