Or is it only the listing that het postponed while the TGE itself already done?
The TGE is even not conducted yet, as I see in their guide article
https://beyondprotocol.medium.com/uniswap-and-beyond-how-to-buy-bp-3f9d66b904e4 that currently the newest one, at the beginning they say "For those whod like to participate in our TGE" based on this I strongly believe, TGE is not launched yet.
Their TGE will be in Uniswap, as they say again "Liquidity will be added at Monday, October 4, at 6:30pm PST"
Looks like token will be transfered to there later.
