Ethereum ETH $4 001 24h volatility: 0.3% Market cap: $483.75 B Vol. 24h: $43.12 B price climbed above $4,000 on Tuesday, October 21, posting a 3% daily gain amid a broader market rebound. The upside momentum followed SharpLink Gaming’s announcement of fresh ETH acquisitions, strengthening bullish sentiment around the second largest cryptocurrency by market cap.
In a post shared on X (formerly Twitter), SharpLink Gaming disclosed it had purchased 19,271 ETH at an average price of $3,892, bringing total holdings to 859,853 ETH, worth roughly $3.5 billion as of October 19, 2025.
The company’s treasury update also highlighted positive staking performance, with 5,671 ETH earned in rewards since June 2.

SharpLink’s ETH concentration ratio has doubled since June, now standing at 4.0, reflecting aggressive treasury expansion. The firm also raised $76.5 million at a 12% premium to market, reinforcing market confidence in Ethereum’s institutional appeal.
ETH trades near $4,020, maintaining strong footing above its 50-day moving average, while traders eye potential retests of the $4,200 resistance.
As Coinspeaker reported on Tuesday, Bitmine, Ethereum’s largest treasury firm also announced fresh ETH buys worth $250 million, bringing its total reserves to $13.4 billion.
Derivatives metrics show a considerable increase in Ethereum trading activity on Tuesday, but limited evidence of long-term capital inflows. Coinglass data reveals a sharp 37% rise in Ethereum futures trading volume, but only a modest 1.77% increase in Open Interest (OI), bringing the total OI to $44.74 billion.

This imbalance indicates that more of the intraday market activity came from ETH traders repositioning existing contracts, rather than new inflows.
Meanwhile, the long/short ratio sits at 0.94, reflecting a slight bearish bias as short traders maintain a marginal edge. This suggests that, while Ethereum’s spot market momentum leans positive, derivatives traders remain cautious.
Failure to close above $4,000 could see traders unwind more positions, giving way to retest of the $3,900 levels. On the upside, the build of short-positions increases the likelihood of a rapid breakout to $4,200 if macro catalysts trigger a short-squeeze.
