Short answer: there are a lot of red flags around BlockDAG. I wouldn’t call it definitively a scam—there are mixed signals—but the risk of losing money looks high. Here’s the balanced view with receipts.

Promises vs reality (as of Aug 15, 2025)

Bottom line: could it be a scam?

How I’d de-risk (if you’re still curious)

  1. No FOMO. Don’t buy on marketing headlines or “last batch” pricing.
  2. Seek third-party confirmations:
    • Published audit PDFs (scope + findings) for the actual L1, not just a token.
    • Exchange announcements from the exchanges themselves.
    • Public testnet/mainnet repos, commits, contributors, and working nodes.
  3. Check on-chain flows: Can you see presale funds in verifiable wallets? Any multi-sig? Any spending?
  4. Withdrawal reality: If there’s any vesting/claim portal, can early users actually claim and move tokens?
  5. Position sizing: If you must punt, keep it tiny, assume a total-loss scenario, and avoid referrals/lock-ins.
