U.S. spot Bitcoin (BTC) exchange-traded funds pulled in $1.32 billion in net inflows during March, even as gold ETFs shed $2.92 billion in the same period — a divergence that Bloomberg analyst James Seyffart says signals Bitcoin's expanding role as a multi-purpose portfolio asset.
Bitcoin ETF March Inflows
The contrast emerged from monthly fund flow data that Seyffart discussed on the Coin Stories podcast, published to YouTube on Friday. He argued the gap reflects more than a one-off blip.
"There are just more use cases of why somebody would put a Bitcoin ETF in a portfolio," Seyffart said.
Gold's March was rough. On Mar. 4, GLD — the largest U.S. gold-backed ETF — recorded a $3B single-day outflow, its steepest withdrawal in over two years.
Data cited in mid-March reports, showed Wall Street had been accelerating gold sales over the prior four months. Retail buyers, meanwhile, were purchasing the metal at triple the pace seen six months earlier.

Seyffart Bitcoin Portfolio Case
Seyffart drew a simple contrast between the two assets. Gold is widely viewed as a hedge against inflation and currency debasement — and little else.
Bitcoin, he argued, serves different purposes for different investors. Some treat it as a store of value. Others use it as a growth bet or a way to position around liquidity conditions. Still others hold it as digital property or capital.
"It can be hot sauce in a portfolio," Seyffart said, noting that Bitcoin's volatility and return potential can boost overall performance for those willing to carry the risk.
Based on that reasoning, he said Bitcoin ETFs will eventually surpass gold ETFs in total assets under management. U.S. gold ETFs currently hold far more in AUM than their Bitcoin counterparts, so such a shift would be significant.
