Bitcoin Lightning Network capacity hits record as Tether backs Speed

Bitcoin rallied 15% to above $64,600 on July 10, spurred by strong ETF inflows and fresh optimism from Tether’s $8 million investment in Lightning‑focused startup Speed [1][2].

What drove the move

ETF inflows have been a primary lift, with single‑day purchases ranging from $221 million to $300 million and weekly totals topping $1.347 billion [1]. Those funds have helped Bitcoin break past the $58,000 mark it sat at on July 1, pushing the price toward the $65,000 psychological ceiling. At the same time, Tether announced an $8 million lead investment in Speed, a Lightning‑based payments platform that processes over $1.5 billion annually and serves 1.2 million users [2]. The backing signals confidence in Bitcoin’s layer‑2 ecosystem and adds a narrative of expanding real‑world utility for both BTC and USDT.

Lightning network gains momentum

On the same day, Lightning’s on‑chain capacity rose to a new all‑time high of 5,637 BTC, eclipsing the previous peak set in March 2023 [3]. The surge reflects institutional players such as Binance and OKX moving more BTC into Lightning channels, even as node counts remain below earlier highs. The capacity increase coincides with Tether’s Speed funding and Lightning Labs’ release of Taproot Assets version 0.7, which adds multi‑asset support and reusable addresses, positioning Lightning for higher‑value transfers beyond micropayments [3].

Price context and near‑term outlook

Bitcoin’s rise to $64,600 sits just below the $65,000 resistance that, if breached, could trigger a “higher high” relative to the June 22 peak [1]. Analysts note that a move above $65,600 would be meaningful, but a decisive break would require clearing the $67,300 lower high from June 15 [1]. The current rally appears tied to short‑term sentiment improvements rather than a sustained trend, with some observers warning that macro conditions will dictate durability [1].

What to watch

• $65,000 resistance: a clear break could open the path to $67,300 and higher.
• Institutional Lightning deposits: continued BTC inflows into Lightning channels may push capacity beyond the current 5,637 BTC record.
• Regulatory developments: any advance on the Crypto Clarity Act or related ETF rulings could reinforce the bullish momentum seen in recent inflows [1].

The convergence of record Lightning capacity, a major stablecoin issuer’s investment in layer‑2 infrastructure, and robust ETF inflows underscores a growing belief that Bitcoin’s scalability is becoming commercially viable, even as the market watches whether price can sustain the breakout.
