I mean it literally disappeared. The exchange said it would no longer support the coin and I needed to move to another exchange. When I tried to transfer the coin to another exchange it just disappeared right before my eyes. I could not find it in my history. It was like it never existed. It was not enough money to waste any more time fooling with it. I transferred every other coin I had on that exchange and never went back. Lesson learned. As for difference between LCO and STO, that is above my pay grade.
