STON.fi REVIEW

Our experts rate STON.fi as an exchange with a basic level of reliability and security, which may not be sufficient for risk-averse users. This often reflects the absence of Tier-1 regulation — that doesn’t automatically mean the exchange is unsafe, but Tier-1 oversight generally provides stronger investor protections.

Expert Advice

  • Funds custody & transaction controls
    I advise minimising on-exchange exposure and adding transaction-level safeguards. Keep only trading capital on exchanges and move long-term holdings to self-custody (hardware wallets); for large sums consider insured institutional custody. Use withdrawal whitelists, set conservative daily limits, require multi-step confirmations for large transfers, and test small withdrawals after major account changes. Regularly audit connected apps and remove unnecessary permissions — layered controls reduce the impact if one defence fails.
