I really don't recommend people to connect in public wifi or hotspots that are not trusted. Since, I saw a video on youtube that every transaction people made on that while connected can be viewed by the person with authority. For example, somebody moved his money to his savings account. As much as possible don't connect to public wifi or hotspots. Scammers are everywhere. And what if you are connected to a person that is an IT or a computer engineer and hacks you.
