Nice find.

I just read their whitepaper. They obviously wrote it in a hurry, they claim on Twitter that this is their revised version.
A lot of typos, "Quater" (sic; Quarter), "Shippment" (sic; Shipment) and they claim to have integrated "Montero" (sic; Monero) into their wallets and systems, a task everybody has failed after months of work, as far as I know. Monero is tricky to integrate, in part by design.

I can't find their Beta wallet to test, I can't find a review or test of their first (Beta?) cards. They make it very hard to find information on their website and in their whitepaper.

They claim a lot of rewards, indeed very nice, but I seriously doubt that they are able to deliver based on what they have now (which I can't find and/or find doubtful).

Based on this, I will not participate in their ICO. I will wait for them to deliver something more than a website and a whitepaper with typos. TenX delivers all the time. I don't see Centra as real competition for TenX (for now).

But: Everybody is free to invest in what they think is right for them, I am not your financial advisor.
