my $record = $cat->by_ticker("eth"); # alias for by_symbol(), lowercase also works

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). This catalog is updated to the list on CMC as of Jan 6, 2018 (1384 coins and tokens).
CMC does not provide unique symbols nor unique names, only unique "safenames" (slugs). Whenever there is a clash, this catalog modifies the clashing symbol and/or unique name to make symbol and name to be unique again (usually the coin/token with the smaller market cap "loses" the name).
There is no guarantee that the symbol/name/safename of old/unlisted coins or tokens will not be reused.
