I agree to this. When we are making signing transactions it is kinda risky sometimes. Our wallet can be easily detected and hacked. But since the other is only used by monitoring then yes it is safe. For me it is also OK to put my wallet on my mobile phone coz unlike desktop or laptop or pc, I can bring it everywhere. But of course I am very carefulcoz I might misplaced ot lose my phone which happened to be my everything.
Using a mobile wallet is indeed more efficient, practical and portable. The risk of a mobile wallet certainly depends on the security of the smartphone and also depends on the user. Do not install third-party applications that you do not trust. To anticipate when the phone is lost, use screen lock security and make sure your phone is still connected to the internet to keep track of it when your phone is lost.
