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.

Regular hardforks to bail out larger losses by e.g. ETH foundation. Source of the ICO bubbles. Multiple client implementations which fail against each other in terms of consensus errors regularly.

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.
