Hi,
Every exchange adding a new btc, eth, token address on the exchange website.
I think they need some private key to set the transaction on this websites.
So is this private key stored in a normal database?
And is this safe?
Safe or not dependent on the exchange developer, if the developer intends to be evil then all your accounts will not be safe. the account that we have should always be given additional security such as 2FA so that only we can access
