Bitcoin.org Hit With DDoS Attack, Bitcoin Demanded as Ransom
Bitcoin.org is being hit with an "absolutely massive" distributed denial of service attack, according to the site's pseudonymous operator.
Shortly after being entwined in a legal decision in the U.K., the Bitcoin.org website has faced another battle, this time on the technical front.
According to the site's pseudonymous operator, Cobra, Bitcoin.org was hit with an "absolutely massive" distributed denial of service (DDoS) attack. CoinDesk was able to access the site without issue.
Decrypt reported on Monday that attackers had demanded 0.5 bitcoin ($17,012 at the time) to have the site's services and operations restored to normal.
CoinDesk attempted to contact Cobra to discuss the issue but did not hear back by press time.

I don't think I've been this offended in a while. Ungrateful scum.
DDoS is a type of cyber attack that targets a site's host or its infrastructure by flooding the host with request traffic that then overwhelms the system and renders it inoperable.
The attack is the latest development for the site, which is designed to educate and instruct others on how to buy and sell the crypto.

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.
