As always the question is whether you are investing or speculating. This is probably NOT a good time to speculate on ICOs. The market is really flooded right now keeping the prices low. If you have down research on the company and believe in the project, then there is no reason not to invest. If the project is successful, it is reasonable to expect the coins to appreciate over time and getting in early is the best way to increase your ROI.
For instance, Qchain and BitDegree both have chances to be very successful, sustainable businesses and I expect that over a long time horizon, their tokens will appreciate substantially. Qchain just started their ICO. You can read more or check out the ICO at
