Bitcoin, the original crypto rebel, is racing into the heart of the financial establishment with an exchange-traded fund that tracks its price. But will it strike gold?

The world's biggest cryptocurrency has leapt 28% in October, with investors betting U.S. regulators will give the green light for a spot bitcoin ETF and thereby unleash a new wave of demand.

How much cash could such a fund reel in, though? Well, it's hard to say, judging by the wide assortment of estimates from market players, ranging from $3 billion on its first day to $55 billion over five years.
