Like everyone else here, I am no expert. From my perception though, crypto-currencies do not follow the standard model of economics that a lot of our Fiat infrastructure is built on. The relative net worth of a coin is not dependent on market cap or supply, but really more dependent on irrational internet hype of the coin. So although I do agree with you that such a small market cap can leads to big returns, that market cap in and of itself doesn't make that coin more popular and hence more valuable.  

I've not looked into the details of this coin you mentioned. I don't even think looking at market caps and buying based on them is a bad idea... I do that too. Just throwing my 2 cents out there that internet hype is worth more than market caps.
