Upon finding information about them, I landed on ANN thread here in the forum which they were actually dong bounty campaign where they paid CATT tokens to their participants. Unsure what happened but they already lock the ANN thread but they are also offering daily dividends to the holders of the coins just like the new exchange projects concept like Vitex. Interesting they are not actually the first to have offered dividends to token holders. My guess is that the holders of CATT are trading there.
