Bitcoin cash is essentially printing money

The creation of a second bitcoin asset this week did almost nothing to dilute the price of the original unit, with the value of the new asset instead rocketing skyward, generating almost $US7.5 billion ($9.5 billion) out of thin air.

This week, a group of bitcoin activists and developers created a second version of bitcoin, within a few hours, the value of the new unit – bitcoin cash – leapt to over $US600.

The "fork" – instigated by some bitcoin miners as they ran different software to generate different sized blocks – meant bitcoin cash essentially inherited a similar amount of coins in circulation: about 16.5 million units.

Calculating the market capitalisation of cryptocurrencies is similar to that of a stock's: you multiply a coin's price by the total supply of coins in circulation

But unlike when a company issues more stock and the price re-rates, bitcoin simply cloned itself and the market instantly ascribed value to the new asset.
