Arionum is one of the best cryptocurrency to invest in 2018, with his lower price 0.0.02$ and small marcketcap 1M$ you can make profit of 50x easy.
ARO could indeed be a huge sleeper with the possibility of seeing some high gains in a bull market. The price is really low because of the latest exchange issues and the team is working very hard. I really like the new homepage and the fact that it was not really expected is just a cool thing. The team is doing a great job and I can´t wait for the marketing campaign to start. Maybe some further exchange listing, hackathon etc
