This article aims to list relevant cryptocurrencies, even those too minor to have their own wiki entry. See also [[:Category:Alternative cryptocurrencies]]
The cryptocurrency market is explosive which currently serves hundreds of currencies. Almost all of them are obvious scams—including many which purport to have a large market cap. This article aims to list only the most relevant cryptocurrencies in terms of novel technological advancements or strong engineering teams, or due to widespread awareness thereof. Direct, low-level scams should not be listed here.


It is based [https://bitcointalk.org/index.php?topic=134179.0 on this thread].

The cryptocurrency market is explosive which currently serves hundreds of currencies. Almost all of them are obvious scams—including many which purport to have a large market cap. This article aims to list only the most relevant cryptocurrencies in terms of novel technological advancements or strong engineering teams, or due to widespread awareness thereof. Direct, low-level scams should not be listed here.
