Daily brief: Binance hack denial, Tether's bitcoin stash, Mercado Bitcoin pledge

CoinDesk's daily video brief recaps three developments. North Korea denied involvement in the $6.4 billion Binance hack despite the FBI's attribution of the Oct. 29 heist to its TraderTraitor group. Binance has reopened withdrawals after a 45-hour freeze and absorbed the losses, replenishing roughly 95% of the stolen assets.

• Tether CEO Paolo Ardoino revealed the company holds about 150,000 BTC (~$11.5 billion) — roughly 50,000 more than its latest reserve report implies — with the extra coins held outside USDT backing as proprietary investments.
• Mercado Bitcoin pledged to cover all user losses after wallets on at least 10 chains were drained of about $40 million, with Tether, Circle and Chainalysis helping freeze roughly $11 million of the stolen funds.
