I got in at pre-ico and the team well what can I say, they keep promising the cards then delaying promising delaying. The cards were meant to be sent out before Christmas then they changed it to early Q1 now its Q2. I was around quite a while in slack and I would be very wary of this behavior they just seemed like a bunch of smooth talkers they promise alot and deliver on very little which is why the price has gone like it is. In  pre-ico price was around .66cents and the main sale was $1.23 although the price did spike upto $3-$4 for a brief moment majority of the time the price was under ICO price.  If you look where the price is now Public confidence with Centra is extremely low so having the price go x10 is unlikely, I wouldn't go as far to say its a scam but it feels like they are trying to run a legitimate type of business without a product to avoid it being called a scam.
