Bitcoin investment products see another record $2.9B in revenue.

US spot Bitcoin (BTC) investment products had another record weekly inflow, with $2.9 billion in new assets added.

In the year According to a March 18 report by digital asset investment company CoinShares, a total of $13.2 billion in new capital has flowed into investment products such as spot bitcoin ETFs, which are now pegged at $74.61 billion worth of bitcoin. Bitcoin products account for 97% of total revenue. “Digital asset investment products hit a record weekly inflow of $2.9 billion,” said CoinShares analyst James Butterfield.

Surprisingly, Ether (ETH) and other altcoin investment products have not been popular with investors, whose year-over-year inflows are a small fraction of the total inflows into Bitcoin. Additionally, despite all-time high ETF inflows, the price of Bitcoin fell 7% last week and is now trading at $67,418 at press time.

Outside the U.S., crypto exchange products saw a record exit, with investors buying $738 million worth of bitcoin on German, Canadian and Swedish exchanges and swapping some of it for their American counterparts. Compared to management fees of more than 1% per year, US Bitcoin ETFs charge 0% of the portion you invest. After being approved by the Securities and Exchange Commission in January, US Bitcoin ETFs have taken over 80% of the spot Bitcoin ETF market share.

The popularity of Bitcoin ETFs has led regulators such as the UK's Financial Conduct Authority (FCA) and Hong Kong's Securities and Futures Commission (SFC) to soften their stance on such products. On March 11, the FCA said it would not object to “requests from recognized investment exchanges (RIEs) for cryptoasset-backed Exchange Traded Notes in the UK listed market segment”. Similarly, the Hong Kong SFC will accept the first spot Bitcoin ETF application on January 29.
