Inflows into digital asset investment products hit a record $44.2 billion in 2024, led by U.S. spot-based ETFs, despite some market volatility, data shows.

The year kicked off strong, with $585 million flowing into digital asset products during the first three days of 2025, according to data from European asset manager CoinShares. However, for the full week, which included the last two trading days of 2024, there were net outflows of $75 million.

CoinShares head of research James Butterfill says 2024 ended with a record $44.2 billion in inflows into digital asset products, which is almost four times higher than the “prior record set in 2021 which saw $10.5 billion inflows.”

A big chunk of this surge came from U.S. spot-based exchange-traded products, which made up all of the inflows, totaling $44.4 billion. Switzerland saw some smaller inflows of $630 million, but large outflows from Canada and Sweden — $707 million and $682 million, respectively — balanced things out as investors shifted to U.S. products or took profits.

Bitcoin (BTC) continued to lead the pack, accumulating $38 billion, or 29% of total assets under management. Even with rising prices, short-Bitcoin products saw smaller inflows of $108 million, down from $116 million in 2024, the data shows.

Ethereum (ETH) made a big comeback in late 2024, with $4.8 billion in inflows, nearly 2.5 times more than in 2021 and 60 times more than in 2023. It surpassed Solana (SOL), which saw only $69 million in inflows. Altcoins (excluding Ethereum) brought in $813 million, accounting for 18% of total assets under management in 2024.
