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
This is the downside of exchanges, it requires you to provide your information, otherwise, they won't accommodate, you making it seem like transacting with banks because of information providence that's needed that you won't need to experience when you are using mixers. Well, since margin trading has initial trading that makes it close to the concept of leverage, you'll really be needing to have a trading account. In other words, to create leveraged trading you have to use margin trading accounts, the created leverage will tell the ratio of borrowed funds to the margin, therefore your data will really be needed.
