Cyber Security Act 2023 (CSA): This is the primary legislation governing digital activities and data security. It replaced the controversial Digital Security Act 2018 (DSA). The CSA makes it an offense to "collect, sell, keep possession of, supply or use identification information of another person without lawful authority or explicit consent." Phone numbers are definitively considered personal identification information.
Data Protection Act 2023 (Draft): While still a draft, this proposed law further solidifies data protection principles in Bangladesh. It emphasizes that consent for data processing must be "free, specific, clear, and capable of being withdrawn," and the burden of proof for consent lies with the data controller. It also states that no data should be disclosed without the data subject's consent for any purpose other than the original processing purpose.
Therefore, attempting to obtain a list of cryptocurrency users' phone numbers without their explicit, informed consent and a lawful, recognized purpose would be a direct violation of Bangladeshi law, carrying significant penalties.
3. Exchanges:
Global Privacy Standards: Major cryptocurrency exchanges (like Binance, Bybit, OKX, etc., which are accessed globally, including from Bangladesh, despite local regulations) operate under stringent international data protection standards (e.g., GDPR in Europe, similar laws in other jurisdictions).
Strict Non-Disclosure: These exchanges are legally and ethically obligated to protect user data. They do not sell, rent, or provide lists of their users' phone numbers to third parties for marketing or other unsolicited purposes. Sharing such information would be a massive breach of privacy, security, and trust, leading to severe regulatory fines and reputational damage.
Limited Phone Support: For security reasons, most major crypto exchanges do not offer public xt user phone number list customer service phone numbers for direct voice calls. Their primary support channels are 24/7 live chat and support ticket systems, which provide a written record and are less susceptible to phishing or impersonation scams.
Binance Support: Primarily through 24/7 Live Chat on their website/app. They explicitly warn against phone calls or DMs from individuals claiming to be support.
Bybit Support: Accessed via their Help Center and "Submit Case" webform. They rely on online support.
OKX Support: Available via chat on their website.
4. Scam Alert:
Any individual or service offering to sell or provide a "cryptocurrency user phone number list" is almost certainly running a scam. Such data would be illegally obtained, likely inaccurate, outdated, and using it would expose you to significant legal risks, financial fraud, and cybersecurity threats.
In conclusion:
It is not possible to legitimately or legally obtain "cryptocurrency user phone number data" in Bangladesh. The legal framework prohibits it, and legitimate cryptocurrency platforms do not provide such information due to their privacy and security policies. You should absolutely avoid any attempts to acquire or use such data.
