No centra is not scam but SEC had issue with centra tokens also they have done some mistake in marketing centra by claiming mastercard and visa partner . Even Centra had great produuct included more than 15 crypto currencies are spendable assets . But now all the investors money gone .
Mistake? The team was misleading investors on purpose to sell worthless tokens. It is called SCAM, not a mistake. I wonder why CTR is still traded on HitBTC and Cryptopia, and it's price even goes up... This exchanges should delist it immediately like Binance did. BTW the red flags was present before tokensale started, if anyone did the research.
