Comparison of cryptocurrencies

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

It is based on this thread.

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)
