Yeah, like many blockchain projects (heck even you just look at plain old Bitcoin) many parts of the world or markets don't need decentralization nor blockchain tech (at least yet) as modern industrialized countries have most basic things sorted out for most people. In emerging markets and especially 3rd world countries though there's so much that can be improved with peer-to-peer/blockchain tech. Dent lowering the cost of data can/will be huge; in many parts of the world a mobile phone is the only connected communication device. There are no laptops, desktops, tablets in use so to speak, due to lack of availability, and high purchase and service costs. So the population relies solely on mobile phones for pretty much everything. Another segment that will include even industrialized countries in which Dent can make a dent (puns, yay!) is Internet of Things. All of them. All the time. Through Dent Exchange. Mind blown. So next time you debate your friend, use something to pry his mind open a bit wider
