By next year we shall see the result of the Libra development and if its going to be a successful launch, do you think one day we shall see a facebook login button on exchanges like binance? Would you login to it?
I have seen this on websites like medium.com. Worse is taht not only binance but also kraken and bittrex If you have all your personal details on your Facebook account, it's better not to use that login features, the exchange will see your friends list, trace your location and some personal data and besides Facebook hacking is very prevalent, it's much better to use your email with the authenticator turned on.
