The net flow of spot Bitcoin ETF is currently $44 billion, and the size of BTC ETF is almost half the size of all gold ETFs

According to HashKey Exchange's social media post, the net flow of spot Bitcoin ETF is currently 44 billion US dollars. This means that in a little over a month, the size of BTC ETF is almost half of all gold ETFs. Bitcoin is often referred to as "digital gold" because it possesses scarcity, durability, unforgeability, portability, divisibility, and verifiability. In fact, Bitcoin is even scarcer than gold: for hundreds of years, the supply of gold has been increasing at a rate of 1% to 3% annually while the supply of Bitcoin decreases by half every four years.
