Re no 3 - Would it not make more sense to buy them from ccex?
TAM will no longer be on btc exchanges in the future (unless they add it themselfs) The value of TAM will be USD, so i want to stop using btc exchanges for TAM transactions.
so why is it on c-cex now?
I guess it's related to centralization versus distribution of the coin. Since it was initial a PoW the miners had to sell to traders their TAM or otherwise all the TAM would be in the hands of a few miners that mined the coin. This way using c-cex it enables some distribution of the coin to whom is not a miner and wanted to own TAM.
