Why does a coin have a low ranking?

The list of all coins is ranked on market cap and is divided into three different tiers:

Tier 1* - Coins that have at least 3 BTC trading volume, a confirmed supply and a volume / market cap ratio of at least 0.001.
Tier 2 - Coins that fall below the 3 BTC trading volume threshold.
Tier 3 - Coins that have an unconfirmed supply (these supplies are not yet validated by us and could possibly be incorrect).

*Only coins that belong in tier 1 are calculated in the overall statistics, such as the market cap and 24h trading volume.
