By the way, in this case, is it interesting that the permanent issue of tokens will be provided in the smart-contract? After all, we have a one-way direction of motion of tokens. I would be grateful if this moment will be explained to me.
Due to the white paper, the reason of issue KGT tokens based on ERC-20 (or on blockchain in general) is to smooth (make it clear and transparent) the process of exchange tokens on in-game chips. Simply saying, no one could make a fake KGT and exchange it on in-game chips.
