Time-dependent weighted directed networks of cryptocurrency interaction from high-frequency returns
Which cryptocurrencies drive the market—and how that power shifts over time
A analysis of five years of cryptocurrency price data reveals a shifting pecking order of influence: Ethereum has become the market's most powerful trendsetter, while Bitcoin's sway has weakened. The researchers mapped these relationships by tracking which cryptocurrencies' price movements predict others', uncovering a tiny handful of coins that shape the entire market.
Traders and fund managers who want to anticipate crypto market moves need to watch the right assets. Bitcoin is no longer the dominant signal it once was—ignoring Ethereum's emerging role would mean missing early warnings of broader market shifts. This snapshot of a fast-changing hierarchy also flags a real risk: when power concentrates in a small number of assets, the entire market becomes more fragile.
