Yes, I was prepared to transfer my entire Zecco account and they said they would not accept STAU or a couple other's that have DTC chills in effect. All brokers I've talked to are getting really nervous about microcap stocks. It's such a shame since I've made great returns and had a blast since I retired. I'm about done with the stock market and have been stacking physical metal fast and furiously, so I suppose that's the best avenue for my energy and money. I urge other's to investigate holding silver and gold for just these reasons: no counter party risk as long as you keep it under your control.
