What would you do if someone approached you with a crazy offer to buy your website? At times this can be tempting but I don't know what I'd do if such an offer came my way. Would it be a problem if I went ahead and opened another website in the same niche?
It wouldn't be a problem as long as you did not sign to a "No compete" agreement. Only agree to a no compete if the money is good enough. Most no competes are for 2 years.
