  • SpaceChain's International Space Station-hosted (ISS) hardware authorized a 0.0099 BTC (about $92 at the time) transfer initiated by Chief Technology Officer Jeff Garzik on June 26, the decentralization company disclosed Tuesday.
  • Developed by GomSpace and installed on the ISS on June 25, that hardware holds a private key needed to verify blockchain transactions via the "multi-signature" technique.
  • Data can only reach the ISS via the craft's encrypted ground station links. SpaceChain says this adds security and resilience to transaction authorizations.
  • Representatives did not immediately answer CoinDesk's questions as to why a transaction initiated on June 26 was only made public nearly two months later.
  • Although the ISS hardware cannot communicate with other crafts, SpaceChain hopes to build and launch robust decentralized blockchain infrastructure that can 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.

Gold tops $5,000 as bitcoin stalls near $87,000 in widening macro-crypto split: Asia Morning Briefing

Bitcoin’s onchain data points to supply overhang and weak participation, while gold’s breakout is priced by markets as a durable macro regime shift.

What to know:

  • Gold’s surge above $5,000 an ounce is increasingly seen as a durable regime shift, with investors treating the metal as a persistent hedge against geopolitical risk, central bank demand and a weaker dollar.
  • Bitcoin is stuck near $87,000 in a low-conviction market, as on-chain data show older holders selling into rallies, newer buyers absorbing losses and a heavy supply overhang capping moves toward $100,000.
  • Derivatives and prediction markets point to continued consolidation in bitcoin and sustained strength in gold, with thin futures volumes, subdued leverage and weak demand for higher-beta crypto assets like ether reinforcing the cautious tone.
