I just saw this post and it's totally misleading. If you want to invest in Graphene through crypto, I remember that there is one project called TecraCoin. Just to contribute, I had my eye on projects in Science and Technology since I agree that when we help our fellow scientists and engineers by investing to their research, or giving them financial support -- it might go a long way. They do solve problems like hastening of legal processes from the research's inception to its commercialization, or helping these geniuses to create a better world one step at a time. I know it's a vague explanation but you can check more details here and do your own research.
