The $TGT has not started yet, and the TGE is actually not worth it, as it requires staking 3 BNB and you cannot monitor how many people are claiming. In contrast, the airdrop from the alpha exchange is worth it because you can monitor the number of claims to determine if it's worth claiming. If there aren't many people, you can also reissue the airdrop. Overall, it's still better to directly claim what the exchange has sold.
