This article aims to list relevant cryptocurrencies, even those too minor to have their own wiki entry. See also Category:Alternative cryptocurrencies

Currencies

The order / grouping of these coins are still TBD.

Ripper234 proposes a grouping of Major, Minor and New by an arbitrary market cap limit. This can be done once the market caps of the alts are known.

Using market cap will make Tonal Bitcoin a "Major" despite de facto minor usage. Therefore, I suggest finding a different method of categorizing. --Luke-jr (talk) 05:06, 4 March 2013 (GMT)
