Anyone can make a mistake; remember the people that asked for the money back after the ICO? All they can do now is move on or buy in higher. As long as they are not spreading FUD, I will not call them a losser.
This is a fair point. IMHO based on the where this project is going and the technology which stands behind the name, it's probably not a bad idea to buy in even now. I know we're sitting at 20k but ARK has much more growing to do. Time spent here is evidence of that. This place was almost annoying to check back in late March because of all the people requesting money back. They all have their reasons, but it's still not too late. (Also, it's helpful to view ARK not JUST as something to make profit. There is useful tech behind it).
Happy Easter weekend.
