Do your own research, look into the whitepaper, the team and how they are marketing. Also the most important thing is if they actually need a cryptocurrency. If they don't they are only doing it to raise money in an ICO.
I am waiting for Crowdholding. Great whitepaper, nice ideology and a strong team who is working organically to market their ICO. Launches on the 1st of November.
