That first wave of bitcoin ETFs attracted a whopping $65 billion in 2024, helping to propel the price of bitcoin from $43,000 to more than $100,000. The largest of those new products, BlackRock's iShares Bitcoin Trust, has become the most successful debut in the ETF industry's 35-year history. Shortly after those products celebrate their first anniversary on Jan. 10, President-elect Donald Trump - who has pledged to be a crypto president - will be sworn in for the second time, igniting what cryptocurrency fans believe will be a new golden era for the digital asset class.
