I just recently finished the grind towards level 50 (and believe me, it's a grind -- level 42 is halfway...) and can say that you shouldn't have anything to worry about. This game is peer-to-peer, as far as I can tell, meaning it won't ever be shutdown. The leaderboards (where you would check how much online experience you have) might be but I doubt it, as I suspect Codemasters would have done it by now. So yeah, if you think you're up for the grind then I don't see why you wouldn't be able to go for it. I don't see it being shut down anytime soon.
Hope that helps. :)
