Cathie Wood's ARK Invest files paper with US SEC to create Bitcoin ETF

Under a header titled 'Risk Factors', Ark Invest acknowledged the volatility associated with the cryptocurrency.

"Bitcoin has a relatively limited history of existence and operations compared to traditional commodities. There is a limited established performance record for the price of bitcoin and, in turn, a limited basis for evaluating an investment in bitcoin," it said.

The firm also noted that the market value of bitcoin is not related to any specific company, government or asset.

"The valuation of bitcoin depends on future expectations for the value of the Bitcoin network, the number of bitcoin transactions, and the overall usage of bitcoin as an asset. This means that a significant amount of the value of bitcoin is speculative, which could lead to increased volatility. Investors could experience significant gains, losses and/or volatility in the Trust’s holdings, depending on the valuation of bitcoin," ARK Invest said in the filing.
