I bought a domain name that is an exact match for keywords with a CPC of over $1k... Should I park the domain and try to earn income, sell the domain to someone who wants to try their hand at this, or create content and place google adsense on it?
You aren't going to make income parking the name unless it already has traffic coming into it. If you want to get rid of it you could try selling it but that would require searching and contacting end users. The fastest and (probably best) option would be to develop it and put adsense on there.
