Here is a list of my High Risk / High Reward coins that I am invested in and think have a chance for Great Returns let me know your thoughts and coins that you like NOT IN THE TOP 100 and under 10 cents
Vsync (VSX)
Instacash (ICH)
Payfair (PFR)
Devery (EVE)
Leverj (LEV)
SHIELD (XSH)
Ravencoin (RVN)
Electra (ECA)
this list is not in any order
Ravencoin does seem like something that is being slept on at the moment. I would definitely buy it at a dip, or as a way to diversify my altcoin portfolio since it seems to be quite promising, and the community is pretty nice as well.
I'd also say that Ignis is a good buy under 10 cents, it has the potential to go into the top 100 mark even though currently it is nearly rank 180.
Remember that this list that OP gave is going to be extremely high risk, you don't want to invest in any single coins on that list without having a diversified portfolio first.
