This article aims to list relevant cryptocurrencies.<br/>To be listed here, a currency must have '''one''' of the following qualities:
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.
*The currency must have a market cap of one million US dollars.
*The currency must be the first to introduce an innovative protocol.
*The currency must have at one point had significant notoriety.
*The currency must have been an infamous fraud.
These coins are currently ordered according to '''Launched''' date.

| BCash is an altcoin based on an old snapshot of Bitcoin's blockchain (2017 Aug 1) with replay protection and an increased block size limit of 8MB. An unusual emergency difficulty adjustment algorithm causes significant periods of hyperinflation. Significant miner centralization; often a very low hashrate. Major proponents deliberately attempt to confuse new users into thinking BCash is actually Bitcoin, especially by using the name "Bitcoin Cash". On 15 November 2018, an airdrop of BCash occurred between two rival factions now called BCash (BCH) and CraigCoin (BSV).

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.
