In January this year the SEC approved spot trading on exchanges of funds invested in Bitcoin, making investment in Bitcoin accessible to ordinary investors. These Exchange Traded Funds (ETFs) raise funds through a share issuance to purchase Bitcoins that are then stored in a secure digital vault. The price of the ETF shares, therefore, reflects the dollar price of Bitcoins, and effectively allows ordinary investors to trade in Bitcoins without incurring the custody risks. With this approval, the crypto asset sector is plainly on a path aimed squarely at the financial mainstream.
