What it returns

Every Grayscale single-coin trust still quoted as a trust (the bitcoin and ether trusts became ETFs and are in etfs): the coins it holds and their dollar value, its share price, its net asset value per share, and the premium or discount between the two, in percent. Largest holdings value first. The figures are for one market close, which can be weeks old: asOf gives its date, so read it before treating a figure as current. Not scoped to any chain.
