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

I don't think Facebook will allow other exchanges to exist if they become most successful in the cryptocurrency market they will create all the the trading platform on their website itself and make the people to convert them into their labra token but the reality of happening is not anyway near to us.
