About Coivio and Ban Zhang
Coivio is an independent educational publication by Ban Zhang (班长). It focuses on three questions for people exploring Binance: how to register safely, how to avoid common account and transfer mistakes, and how trading fees differ from referral rebates and rewards.
Who writes these notes
Ban Zhang is a content creator and ecommerce operator with an interest in technology, AI and independent software development. This site brings that interest in clear explanations to beginner crypto education. It does not claim professional financial qualifications or speak on behalf of Binance.
How to use the guides
Each guide addresses a specific beginner question and links to the relevant official sources. Registration screens, supported regions, fees and promotions may change. Follow the instructions and terms shown by the service available in your actual country of residence.
Interface screenshots are identified and credited in the articles. The cover illustrations are conceptual artwork; they are not screenshots of an account, proof of a reward or evidence of investment results. Any fee calculation marked as hypothetical illustrates arithmetic, not a rate or rebate promised to you.
Independence and referral links
Coivio is not operated by or affiliated with Binance. Mentioning Binance describes the subject of the guides. Educational information is not personalized financial advice, and using a service or referral link does not remove the risk of loss.
If an article contains a referral link that may benefit the publisher, the relationship should be disclosed next to that link. A referral benefit is only relevant when the official offer and your account eligibility confirm it. Do not assume that a code alone guarantees a discount.
Contact and corrections
For questions about an article or to report an error, email coivio@coivio.com. Include the article title, the passage in question and an official source where available.
Please do not send passwords, verification codes, identity documents, wallet recovery phrases or private keys. Coivio cannot access your Binance account or provide account recovery; account-specific issues belong with the service's official support.
