The price of exchange coins, for example, Bgogo, Bitmax, DEX, etc, have skyrocketed in Q3 2019, proving a new trend of ICO projects: exchange coin. What do you think of this new trend? Will it exist in a long time to come? Please share your idea here 
I also notice that there are at least 7 I know exchanged based ICO and it looks like they are going to be successful but I don't know if there are going to be a thread to big existing exchange now, if anyone of this become huge, there will be more coming in.
