Do you expect a guarantee by somebody for this coin's future, or for any other coin's future ? I am not an expert in the crypto currency world, but I dont have to be one to understand that this is of course a " risk ", just like investing in any other coin is. Nobody can 100% correctly predict the future of any coin, so basically any investment in something that is not " guaranteed " is a risk and there is no exception on this.
What you can do is, do a bigger research on the coin, check out the coin's roadmap on the project's site, talk with the developer/ some other community members that are willing to answer your questions and you will reach a point where you will decide whether the risk COULD be worth in the future or not.
