I think Masternode and new exchanges are more favorite tools for scammers. If you see this topic
https://bitcointalk.org/index.php?topic=5212811.0. many people talk about BCNEX exchanges. This is most hype exchanges project and becomes scam. It was very sad when the project already popular and many people trust it, and team decided to scam people
Even though the project when launching ICO was a big success because there were many enthusiasts, but apparently they were operating to deceive people. After this incident maybe in the future the exchange project will be a little difficult to gain more trust.
