Indeed, whoever thinks that CENTRA being one of the successful ICO during its campaign and even promoted by Mayweather will be turned out to be a scam/fraud. We can never tell if the project is legit during its incubation period unless they had successfully delivered their roadmap.
CENTRA, as I know, a sepat price touched $ 4, even at that time many hunters held the coin wanting higher prices, but it did not change. The CEO just cheated on his own project, so this project became a scam that was widely reported.
On the other hand many are happy because they have sold the centra at a high price and even the hunters are a little disappointed because they cannot keep their promises.
