What is our ranking methodology?

TL;DR: We rank all coins based on market cap, if they meet a minimum trading volume and pass our filters that prevent ranking manipulation. For price calculation we use volume-weighted averages, using data coming from hundreds of exchanges.

Ranking

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

  • Tier 1* - Coins that have at least 2 BTC trading volume and a confirmed supply.
  • Tier 2 - Coins that fall below the 2 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.

Price calculation

Every 60 seconds we calculate a volume weighted average price (VWAP) of every coin.

Filters preventing manipulation

To avoid short-term manipulation of a coin’s ranking, we’ve put the following filters in place.

  • Coins need to have a trading volume of 2 BTC during a 24 hour period.
  • A price ticker gets ignored when the last price is 50x higher than the previous one.
  • We need to ‘confirm’ the circulating supply

Data sources

  • (De)centralized exchanges for price determination
  • Block explorers for supply determination
  • Community input, like coin descriptions, icons, websites, socials etc.

Wash trading

There have been multiple reports of wash trading on cryptocurrency exchanges. The report from the Blockchain Transparency Institute is one of these.

We are dedicated to bring more transparency into the cryptocurrency market. That's why we are looking for ways to filter out wash trading behaviour.

If our community reports verifiable instances of wash trading on specific markets, then we will take appropriate measures against the trading markets in question.
