Bitcoin spot exchange-traded funds (ETFs) were off to a remarkable start as trading officially began on Jan. 11 with a total volume of around $1.6 billion just minutes after the opening bell.
The movement comes on the heels of the United States Securities and Exchange Commission's approval of the first Bitcoin spot ETFs.
