It feels very much to me that they want to monetize their users a lot under any circumstances. There are a lot of ads in their app for all their services.
They already started with the enshittification of their app and it feels like they have a lot more planned.
If you think this does not bother you it can be a good app. I don't think I ever heard anything about them being involved with a crypto scam. They are a real bank afaik and fall under bafin regulations.
