If it was not your intention to imply your crypto scheme was as safe as a bank account or a traditional bank product like a CD, you did a bad job of communication what you were trying to say.
If you communicate (however unintentionally it might have been, I'll grant you the benefit of the doubt) like a sucker roped into ponzi scheme, it's only rational to assume you are one.
I didn't care about the details of your speculative business, I cared about the giant red flag you raised when you compared what you were doing to a bank offering.
