Messari CEO Ryan Selkis is boisterous and sometimes brash, but few are as informed. Perhaps this is because of his institution-grade data firm, which covers the industry like no other, or because Selkis still blogs most days about the crypto things that caught his eye. These Two-Bit Idiot “Unqualified Opinions” have sway.

Selkis was a major voice behind crypto’s political awakening this year and fight against the harmful provisions in the bipartisan infrastructure bill. Selkis delivers (take the Consensus-like crypto conference Mainnet), but his Senate run ambitions (probably just Twitter-talk) look to be on hold. For now.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

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.

What to know:

  • Polymarket and similar platforms are considered unlicensed gambling operators, leading to blocked access.
  • Legal changes are unlikely in the near future, as Parliamentary revisions to gambling definitions are extremely improbable during wartime, leaving prediction markets in a legal deadlock.
