Frequently Asked Questions
What is a White Hat hacker?
A White Hat hacker is an ethical security researcher who intentionally seeks out vulnerabilities in a system to help the organization fix them before malicious actors can exploit them. Many exchanges run bounty programs to reward these researchers.
Is my money safe if the exchange is hacked?
It depends on the exchange's policies. Platforms like Gemini and Coinbase offer insurance on custodial assets, which can cover losses from a breach of the exchange's security. However, this insurance does not typically cover losses due to a user's compromised personal credentials.
Why is cold storage more secure?
Cold storage keeps private keys completely offline, making them inaccessible to remote hackers. This is the digital equivalent of storing cash in a bank vault instead of carrying it in your wallet. It is the most secure method for holding large amounts of cryptocurrency.
What is a bug bounty program?
A bug bounty program is an initiative where a company incentivizes independent cybersecurity experts to find and report vulnerabilities in its software. In return, the researchers receive a monetary reward, helping the company identify and patch security flaws before they can be exploited maliciously.
How important is regulatory compliance for security?
Exchanges that work proactively with regulators often implement stricter security and operational standards, including regular audits and proof-of-reserves. This compliance builds trust and ensures a higher level of accountability, contributing to overall platform security.
Should I use a hardware wallet with an exchange?
For long-term storage of significant amounts of crypto, a hardware wallet is considered the gold standard for security. The best practice is to use a secure exchange for trading and active investing, but transfer funds you wish to hold long-term to your own private hardware wallet.
