in verifying an account in trade exchanges I agree, but the data for verification only between the stock exchange with the owner of an account and publish to third parties either the tax authorities or government financial institutions because we can control the entire transaction in the digital money trading
Provided that used for good as for verifying us, and it could be to investigate fraud cases I think it is fine. However, if the data from the verification misused by certain elements then it will hurt us. Because I heard there is an online shopping site that sells customer data for specific purposes that could harm us. Provided that our data is safe by the exchanger as you say, it would not be a problem. Thank you
