That's funny, i had an encounter yesterday with aoecoin. They are running a scam ico. According to them they are a company with billion dollar tech portfolio, but they don't have a decent website, nobody ever heard about them. I can't find any proof they did some breakthrough inventions. Fuell cells are not invented by them. Solar panels are neither invented by them.
Just look at this shitty whitepaper it speaks for itself:
