DESCRIPTION

This class attempts to provide a list/catalog of cryptocurrencies. The main source for this catalog is the Cryptocurrency Market Capitalizations website (https://coinmarketcap.com/, or CMC for short).

CMC does not provide unique codes nor unique names, only unique "safenames" (slugs). Whenever there is a clash, this catalog modifies the clashing code and/or unique name to make code and name to be unique again (usually the coin/token with the smaller market cap "loses" the name).

There is no guarantee that the code/name/safename of old/unlisted coins or tokens will not be reused.
