A deposit limit is the maximum amount a customer can place into a product or account over a defined period or overall. In savings and fintech products, it caps how much money a user can add, which helps the provider control exposure, funding costs, and operational risk. In the article context, “no deposit limits” means customers are not tightly capped when funding the offer.
In cyber security, deposit limits are a useful abuse-control measure. They can reduce losses if an account is taken over, slow fraudulent cash movement, and make bonus abuse or mule activity less profitable. Attackers may try to bypass limits by creating many accounts, using stolen identities, or splitting transfers across multiple payments. Defenders combine deposit limits with strong identity verification, velocity checks, device fingerprinting, and anomaly detection to spot suspicious funding patterns and stop automated abuse before it scales.
