I found in privacy policy of one particular exchange that it transfers data about me to credit organizations. Actually the same is true for banks.
In what cases do they do this thing? If I make big enough trade volume at exchange, say $50,000 for year, is this information transferred as well? I suppose it happens only if you do margin trading or something... don't know much about it, except that you take loans from brokers...
Yeah I realize $50k is not big for you
We never know until where our personal information are reaching. That is why it is not a good thing to provide it to anyone or any site for that matter that we do not even personally trust. These exchanges, I am referring to centralized ones, are licensed or registered under state policies and regulations. This includes their responsibility to report certain data or statistics or even personal information to the state authorities whenever demanded or necessary. We never know what is happening under the table.
