Justin Tabb is a fraud and a scammer, the devs have not made an update on twitter in over 6 months, and it seems he's now moved on to a new project called Amplify Exchange. This guy literally spent ICO funds to buy himself a house, and then he delayed the V1 release date for over a year until it released (full of bugs), and since then there has not been a word from anybody.
I would beware of Amplify Exchange, since it seems like they are run and made by the same scumbags, so I would not be surprised if it also a full on scam
