- Best Wallet presale exceeds $16.6M amid Ethereum momentum.
Ethereum (ETH) broke past the $4,000 mark on Tuesday, October 21, posting a 3% daily gain amid renewed market optimism. The surge follows major institutional moves, including SharpLink Gaming’s recent ETH purchases, highlighting Ethereum’s growing appeal among large-scale investors.
SharpLink Gaming Drives Bullish Momentum
SharpLink Gaming revealed on X (formerly Twitter) that it acquired 19,271 ETH at an average price of $3,892, bringing its total treasury to 859,853 ETH—valued at approximately $3.5 billion as of October 19, 2025. The company also reported 5,671 ETH in staking rewards since June, emphasizing the profitability of ETH holdings.

Key highlights for the week ending October 19, 2025:

The firm’s concentration ratio has doubled to 4.0 since June, reflecting aggressive treasury expansion. Additionally, SharpLink raised $76.5 million at a 12% premium to market, signaling strong confidence in Ethereum’s institutional viability.
Ethereum’s price now hovers around $4,020, maintaining support above its 50-day moving average, while traders watch potential retests of the $4,200 resistance level. Bitmine, Ethereum’s largest treasury holder, also announced $250 million in fresh ETH purchases, bringing its total reserves to $13.4 billion.
Ethereum Derivatives Suggest Short-Term Volatility
While ETH’s spot market is buoyant, derivatives trading hints at cautious positioning. Coinglass data shows Ethereum futures trading volume jumped 37%, but Open Interest increased only 1.77% to $44.74 billion. This suggests intraday repositioning rather than significant new capital inflows.

The long/short ratio sits at 0.94, indicating a slight bearish bias. Traders are closely monitoring whether ETH can maintain above $4,000; failure could trigger a pullback to $3,900. Conversely, a short-squeeze could push Ethereum quickly toward $4,200 if macro catalysts emerge.

Best Wallet Presale Gains Traction
Amid Ethereum’s price consolidation, the Best Wallet (BEST) presale has surpassed $16.6 million. The multi-chain crypto wallet offers institutional-grade security, non-custodial features, and high staking rewards. With less than 48 hours before the next price tier unlocks, early investors still have a chance to join and benefit from exclusive perks.
Ethereum’s recent climb above $4,000 underscores its appeal to institutional investors and market participants alike. SharpLink Gaming and Bitmine’s treasury expansions provide strong bullish signals, while derivatives markets suggest short-term volatility. Investors will be watching closely to see whether ETH sustains momentum or faces a retest of key support levels.
