1. RBL is way, way ahead than its second and rest of competitors.
2. RBL has 3mil customers at moment, rbl's market has 500mil potential customers, assume less than one of ten can be rbl's customer, that is 30mil.
3. RBL is going to grow its revenue 30% per year, ~8 years time, get 30mil. customers. And you can calculate profits at that time by using current profit/revenue, and give a valuation.
4. And you know what, RBL is building new web site that can handle 10 times +1 traffic as current.

IMO, do your research.
