At this point, Golem is a good investment for the long run. It may not have a good return within a year but down the road of 3-5 years, you can expect huge returns. The project has a good potential and they have good developers and most importantly, the enthusiasm for Golem in the blockchain community is really vast. Don't give up on it yet!! All the best.
I totally agree with you @autodidact88, and I'm not a short term investor, but you'll agree with me nowadays 3 years is a world of time and nobody knows what could happend. In 3 years there could be hundred teams with the same or better idea or technology, and I'm not sure the GNT team could survive so long if the token worths nothing (from there come their salaries)
