Whether or not you purchased a domain for a business related project, or perhaps you acquired it for some sort of personal agenda, gain or spite...we all have that 1 domain name that we hold in our portfolio that holds the most value. Even if you've already sold the domain, whether or not it was for a profit or not and your not the current owner of it, but in the past you were - it still counts. We all have different budgets and risk tolerances but what was the biggest $ dollar amount you've ever purchased a single domain for?, What was the domain? (if your able to say?), What was the niche if any? and how long ago did you buy it? For me, I do have a large portfolio with a concentration on 4L's but yet do I own a 3L so the most I've ever spent on a single domain was 15k on TA**.com which was quite recent, only 2 years ago.
