Oh dear. I don't know what lurks behind the signup page. I hope the strategies are scrupulously legal and kept up to date.
I'm a tax lawyer. I have seen a lot of train wrecks, let's just say.
If the promoter is suggesting anything remotely out of bounds, expect the Department of Justice. You will go bankrupt defending yourself if the DoJ decides to grind you.
Anyone signing up for a tax planning device has become trivially easy to find and prosecute. Subpoena the promoter for records. Find customer list. Launch prosecutors. That's how it worked in the tax shelter days 30 years ago and it still works like that.
I hope the developers have killa legal and tax advice.
