Frequently asked questions
What happens if I lose my Secret Key?
What happens if I lose my Secret Key?
The Secret Key is shown only once at creation. If lost, go to BTC Markets → Account → API Key, delete the existing key, and create a new one. Copy the new Secret Key immediately.
Why must I select Read Only permission?
Why must I select Read Only permission?
