Kik did the first reverse ICO; now YouNow is about to do one. I think we’ll see at least 15-20 more reverse ICOs in 2018. A “reverse ICO” is when an existing company decentralizes itself and issues tokens to its members to stimulate a circular economy. This is as opposed to a ICO from a brand new startup project. All this activity will require the services of a new type of professional — the tokenization consultant — so expect to see that role catch on in 2018, too. For more on reverse ICOs, see here.
