Hi there! The screenshot you provided does not show our official app so I would strongly advise you not to use it if it uses our name as it is most likely a fake platform.
There are many websites and social media accounts that look similar to ours and are trying to compromise our users.
Our official and only Bitstamp exchange app can be found in Google play under “Bitstamp – Buy and sell Bitcoin at Crypto Exchange” and in the App store “Bitstamp – crypto exchange app”.
If you suspect and kind of foul play from the side of the person you’re dealing with, I strongly advise that you contact your local authorities and file an official report.
