Kindly answer me about CEX.IO ... BLOCKCHAIN ?? ETC
in my opinion, nothing was safe on internet, and there are no security that can protect you while you on internet. but as far as i know, if we only one that know what is inside on our wallet, then it will be safe, unless you share what you have to other people. don't put all your bitcoin in one market exchanger. split it and your be good, and if you have android, try to install mycelium to keep your bitcoin. many people recommended to use mycellium.
