I think that's not the only thing to watch out for, because there are many other factors we need to know about this case, the possibility is we open the wallet address anywhere, like using someone else's cellphone, and using someone else's wifi, things like this don't may be done because of the impact you will lose your Bitcoin or Altcoin and you also need to know, you may not download or open a site that you do not know about. so you have to be careful when you do something.
