32150 x 166000 = 5,336,900,000 oz / 21,000,000 = 254 oz per 1 BTC or 254 x $1,600 gold = $406,400 per BTC
if you're going to compare all the Bitcoin there will ever be to gold, you should compare that number to all the gold there will ever be.
the oceans of the world are about 310 M cubic miles. at 25 tons of gold (in suspension) per cubic mile of seawater, that's 7 3/4 billion tons of gold. we'll get it someday, too.
but what'll it be worth?
n.b. - that's just the gold in the ocean. how much is in the crust of the earth, and likewise not yet economically extractable?
also note that there are astronomical bodies - especially in the Oort Cloud, but also meteorites - with known massive, high and easily extractable precious metal content. PMs tend to bunch up with each other, in space or on the earth. here's an interesting wager: how will we first destroy the 'store of value' aspect of PMs? by mining the oceans or by mining space? tough call...
