North Korea Denies $6.4B Binance Hack Role as Tether and Mercado Bitcoin Make News

North Korea says it had nothing to do with the $6.4 billion Binance hack, pushing back on FBI allegations that tied Pyongyang to the massive breach. The denial lands as investigators continue pointing fingers at state-linked actors. CoinDesk flagged the standoff in its latest crypto news roundup.

The Binance figure alone is staggering — $6.4 billion, one of the biggest dollar amounts ever attached to a single exchange hack. Washington's allegation against North Korea is nothing new in crypto circles, where Pyongyang has long been accused of bankrolling its programs through digital heists. Now the accused is talking back.

In a separate disclosure, Tether says it holds roughly 150,000 bitcoin. That's a hefty stack for the stablecoin giant, and it gives the market a rare look at what backs the issuer's balance sheet. Tether's reserves have been a running obsession for critics; this is a fresh data point for both sides of that fight.

Meanwhile in Brazil, Mercado Bitcoin is stepping up for its users. The exchange pledged to cover $40 million in losses tied to a hack — a promise that puts real money behind customer trust. Withdrawals and confidence are usually the first casualties after a breach, so the reimbursement pledge matters.

Three stories, one theme: crypto's biggest players are being forced to answer for security, reserves and accountability. North Korea's denial, Tether's bitcoin pile and Mercado Bitcoin's payout pledge all dropped within the same news cycle. Expect scrutiny on each to keep building.
