I'm taking this app and it's administrative staff at their words when they say that it's free. It's only after I begin trading that I'm firstly solicited for tips, and then told I'm being assessed a surcharge on my trades of crypto. Also, why is it that my financial business is being offered to public scrutiny? The step that comes immediately after selling should be more buying. Instead I'm having to tell the app no, please don't put my investments on blast to thousands of strangers. Needs Work.
