I check the review of the application its look likes they got a good ratings there .
But its looks like just fake rating you should also give negative rate and give feedback to the app so they will not have any victim again.
For download they only got 50 download as of today so its only means this is just a new application make in app store,.
You should always be aware about simple things like how many people use the app before using it or transferring your money.
Reviews can be faked. People can buy review. Or people can use bots to review their apps. Its not that hard. Pay few cents and everyone will jump in to make some fake reviews.
You will see similarities between those reviews which will help you distinguish the fake ones.
And why would you download a well known app that has only 50 downloads (downloads can be faked too though

)?
Well, to be honest, the guy who downloaded should be blamed too for being careless.
