Seeing stuffs like this scares me, because I'm not very familiar with this forum yet, talk more of been tricked,duped or scammed.
You can actually avoid those scam wallet or any applications even you are not lurking much here in the forum by:
- only referring to official download links at the main website
- engaging in the site's official social community group
- asking questions first
Even with how good Playstore security is
(or will be improved in the future), there is no way we can't really avoid encountering these scam apps as fraudsters and scammers will not stop doing that shitty act.
