An ETF is an investment fund that tracks the performance of an underlying asset. That could be stocks, a basket of currencies, a precious metal like gold, or, in this case, bitcoin.

It's a way for investors to get exposure to the value of the underlying asset without directly owning it.

ETFs trade on traditional stock exchanges, and their value should rise when the underlying asset increases in price, or fall if it decreases.

As crypto investors look to assess what the market impact of a bitcoin ETF might be, many are comparing Wednesday's news to the greenlighting of the SPDR Gold Shares ETF — the first-ever spot gold ETF — in 2004.

The total gold market capitalization was worth around $1 trillion to $2 trillion before the gold ETF was approved, and this subsequently ballooned to $16 trillion in a few years after, according to Vijay Ayyar, vice president of international markets for Indian crypto exchange CoinDCX.

"Bitcoin's adoption will be much faster and bigger than that," Ayyar told CNBC via WhatsApp.
