Hello, i would like to ask you why exchanges like kraken and CEX.io ask for personal datas ? what would they do with them ?
I think that if we like to use bitcoin it is because of the anonimity, so don't you think that we should boycot this kind of web sites ?
If they're asking for your personal data, you always have choices like c-cex, yobit, cryptopia and some other.
If you do not wish to share your personal data with them, just stay away from them.
