The lawsuit against Invest Manger alleges the firm promised investors a 12 percent weekly return. The company delivered those returns for a time, building confidence among investors, the lawsuit alleges. But then Invest Manager stopped making payments and was not heard from again.

The people behind Invest Manger haven’t been identified, nor has its headquarters or place of incorporation, Renshaw said. There has been no reply to the complaint, which was filed May 20.

After a legal notice of the suit runs for at least a month, a judge can rule on how much the plaintiffs are owed and give them the green light to purse the funds, which the plaintiffs believe are held in e-Bullion accounts.

The suit does not accuse e-Bullion of any wrongdoing. Rather, it alleges that another company, Invest Manager, ran a Ponzi scheme and that the proceeds of that scheme might be stored in e-Bullion accounts.
