You don't need to invest any money, have an old desktop computer that you use? Laptop? Just run the client and make some coin. End of the day if it turns out it's a horrendous scam/fail, didn't lose much besides some electricity.
Sorry, but no thanks. There are enough warning signs here that I'm not running a binary like that without setting up a VM... and that would be much more work than I could see myself putting into this. All the power to you if you make a fortune out of it, but my common sense is saying "keep your distance".
Would you run if it was Javascript + Java applet running in the browser's sandbox?
Surely you don't run every website in a VM.
