I found a lot of exchanges where users can easily (as they say) buy cryptocurrencies with their bank card. I mean, at binance they request like a lot of data about me, including my phone number or date of birth.
Aren't they selling my private info (that would explain 0,25$ fee on changelly for example), and doesn't that conflicts with the statement about my anonymity?
That would be fair for every fiat-to-crypto exchange, so my question is: do you use it and is it really safe?
No one can assure your documents will be safe forever because you are uploading that in internet.
