Undervalued coins can be a coin with rates equal to the couple of cents (Example , REMME, IOST, UTK, etc) and they are projects with good volume too. Many people think that if the coins value is very less then it cant be good project or something is wrong with them. But no that is not the case, a price tag is not related to that one but its all about the market capital and how the project has distributed the funds in different areas of project.
So if you see an undervalued coin then better to study its agenda first then decide whether you want to invest or not.
Remember once BTC and ETH were also undervalued coins and now see where they are today!
This is just for to know what you guys are missing really!
