Lot of potential altcoins with low cap can be seen around. Not around the top list, but on different ranking. Some are even at 800+ rank. Worthy investment, but we need to have the patience and trust. Few of which are reef, grin, celer network, coin98, steem, and it counts. Right now few are at its best price for entry.
When looking for underrated or gem projects in the market then you would really be needing that effort on finding those gems which means that it would really be needing that time to find those.
Although choosing would really be still depending on you because we do have different criterias and different approach or assessment on different projects that we do able to see
and this is what make things more hard where buying up on coins that we do see that it does have that potential even though its not an assurance but you cant really earn
if you wont really be taking up some risk and this is what you do primarily needs if you are dealing with this unpredictable market.
