Exchange-traded notes for bitcoins (ETN) are now offered for sale by one of the largest US investment companies that manages multi-trillion assets.

Fidelity Investments, which manages assets worth $2.4 trillion, began selling exchange-traded bitcoin notes (ETN) to its customers. The notes are issued by the Swedish company XBT Provider, which is a division of the British hedge fund CoinShares.

Previously, this product was only available in euros or Swedish krona in Europe, but they now appeared in the US market. Bitcoin ETNs were listed on the Stockholm Stock Exchange in 2015.

Bitcoin Tracker One was added to the OTC Market listing under the ticker CXBTF. Any American with an investment account will be able to invest through this tool in bitcoin, technically without buying any virtual currencies.

“Given the current climate on the regulatory front in the U.S., this is a big win for bitcoin,” said Ryan Radloff, the chief executive officer of CoinShares Holdings Ltd., the parent of the company that offers the ETN.

The US Securities and Exchange Commission (SEC) declined to comment on the situation, but market participants assume that bitcoin-ETN's admission to the US market indicates another step of US regulators on the way to bitcoin-ETF approval.
