Bitcoin ETF and mutual fund companies will begin trading on Tuesday after a protracted court battle.

The SEC said on Thursday that the ETFs would begin trading at a rate of 4 cents to the dollar on the Chicago Mercantile Exchange (CME).

The ETFs will have the same price-to-value ratio as gold and silver, but will have lower fees, and will not require the companies to disclose how much they earn.

Goldman Sachs said the ETF would be “a powerful tool to stimulate demand for gold, silver, and other precious metals”.

The SEC added that it would also issue a warning to all investors not to invest in any of the bitcoin ETFs that it has named.

In December, the SEC issued a warning on the use of bitcoin as a form of currency to discourage the use by others.
