Coinbase CEO Brian Armstrong says the crypto exchange will indeed add support for the Lightning Network, one of the biggest endorsements yet for the blockchain that makes bitcoin (BTC) a more realistic option for payments by dramatically speeding up transactions.

The company had said in early August that it was looking into Lightning support. On Wednesday, Armstrong said on X (formerly Twitter) that this review was over and Coinbase has “made the decision to integrate Lightning”

He also took the time to praise bitcoin, calling it “the most important asset in crypto.” Back in August, when discussing the Lightning review, he had said: “I’m all for payments taking off in Bitcoin.”

Lightning is a layer-2 blockchain associated with the Bitcoin blockchain. Bitcoin transactions can be offloaded there for more efficient – and much faster – processing, a prerequisite if BTC has a shot at eventually becoming a common method of payment.

“Bitcoin is the world’s digital monetary system, and Lightning is Bitcoin’s payments layer,” Cathie Wood, the head of Coinbase’s second-biggest shareholder, ARK Invest, wrote on X in response to Armstrong’s post Wednesday. “Coinbase’s integration with Lightning will give its 100 million users an on-ramp to faster and cheaper bitcoin transactions. Hats off to Coinbase!”

Coinbase’s stock was recently up 1.4% following the news.

Armstrong said that while his team is working on integrating Lighting, it will take some time to do so.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

How the ultra-wealthy are using bitcoin to fund their yacht upgrades and Cannes trips

Cometh founder Jerome de Tychey is applying DeFi lending and borrowing on platforms like Aave, Morpho, and Uniswap to structures that help the ultra-wealthy secure loans against their massive crypto fortunes.

What to know:

  • Wealthy investors who hold much of their fortune in crypto are increasingly turning to decentralized finance platforms to secure flexible credit lines without selling their digital assets.
  • Firms like Cometh help family offices and other rich clients navigate complex DeFi tools, using assets such as bitcoin, ether and stablecoins to replicate traditional Lombard-style collateralized loans.
  • DeFi loans can be faster and more anonymous than traditional bank credit but carry volatility and liquidation risks, and Cometh is also experimenting with applying DeFi strategies to traditional securities via ISIN-based tokenization.
