They very much sound like a scam. Or at least, they ain't like it. They have increased the deadline for stage 1 sale without any notice. The got banned in several provinces in Canada and banned in USA. Now with China ban they can't sell to Chinese buyers. Even if they were legit, they'd still most likely fail. But they are not legit, especially, staying behind the shadows. Nobody can legit promise 1300+% ROI in such a short time which they have.
I invested in Plexcoin.
and the thing is, they collected 94% of the funds they wanted
it's almost $2,8 millions
I hope your investment makes a good return for you. I have been meaning to write a post about PlexCoin listing all my concerns and doubts. I just published it on Steemit. Would you care to read my post and give me your feedback? Let's have a healthy discussion. :)
