2017 was the year of ICOs and 2018 was the year of exchanges and stable coins. What is the trend of 2019?

IMO, it's IEO. Basically, IEO is an ICO but taking place on an exchange. BitTorrent is a typical example of IEO. Running on an ordinary blockchain (Tron) but BitTorrent was sold out and flying high in the past few days. Its success was contributed a lot by Binance, where tokens are sold.

Since STO needs a lot of guideline and legal framework from government to be completed, I have a strong feeling that IEO will be the trend of 2019. Your thought?
