It's your investment. All business vary in time to develop, as do markets. This market has just started and the only startups that have made significant achievements commercially with sales are Nanoco, Nanosys, and QDVision. All others are just boasting capabilities until they actually land sales. I personally like my chance with QMC as the qdot market grows. While not leading the industry, they have made steady progress toward commercial success. Hopefully we'll see that success in the next few days, weeks, or months.
