What to Check

Check the token right, issuer or protocol, custody model, private-key control, reserve backing, exchange venue, liquidity, smart-contract risk, regulatory treatment, and whether the asset has an economic claim.

Common Mistakes

  • Treating technical network activity as the same as investable value.
  • Ignoring custody, smart-contract, exchange, and liquidity risk.
  • Assuming a stablecoin, token, or protocol label proves low risk or redemption certainty.
  • Comparing digital assets without checking rights, backing, venue, and jurisdiction.
