In my five years in making money online, i could say that in this business, you should apply the saying that "strike while the iron is hot!" It is not a stable job, i tell you. Today you get a lot of earning opportunities and suddenly they're all gone by tomorrow. So grab any opportunity that comes your way because there is no guarantee they are there the next day. Advertisers come and go. Some last in the business while some quickly disappear. It is a risky business so be careful. Avoid scammers! They're everywhere lurking, waiting for their next victims.
