user7236: This question comes from a lack of understanding of how ratings work.
What is the lowest rating you can get ( or does it never stop decreasing )? 

user4362: If the Elo system is implemented in its purest form, there is no theoretical lower limit for a rating. 
Practically though, every chess organisation implements its rating system a bit differently and often there are rating floors that constitute the lowest possible rating. 
The USCF for example seems to have a rating floor of 100.
