On this Profitable Flips show, we talk to Mark Levine, a newer individual investor who purchased a series of .io domain names that – as a portfolio – have yielded a 100 percent return on his investment in less than a year with a 23 percent sell-through rate. Given that most domain name investors agree that a 2-3 percent sell-through rate is typical, 23 percent is unbelievable. Listen in as we learn from Levine what types of .io domain names do or don’t sell, what types of end users are buying them, how he sets retail pricing, and how his .io investing tactics are going to change in 2017.
