TechFlow reports that HashKey Exchange stated on X that bitcoin spot ETFs have seen a net inflow of $44 billion, meaning that in just over a month, the scale of BTC ETFs has reached nearly half the size of all gold ETFs.
It added that bitcoin is actually scarcer than gold: while gold supply has grown at an annual rate of 1% to 3% over hundreds of years, bitcoin's supply is cut in half every four years.
