Finally, the party #Berachain provided an explanation regarding the Pre-Deposit. If you participated in the Binance Web3 x Stakestone event, you can get Berastone tokens. You should be eligible and claim the token prize $BERA on the Stakestone website. When to claim? Maybe on the 6th or the 7th.
Not a few are also not eligible, either because they left before the snapshot or for some other reason; I myself do not know.
