The post Upbit to Raise Cold Wallet Ratio to 99% Amid Liquidity Concerns appeared on BitcoinEthereumNews.com. South Korea’s largest cryptocurrency exchange, Upbit, announced plans to increase its cold wallet storage ratio to 99%, following a major security breach last month. The announcement comes as part of a comprehensive security overhaul following hackers’ theft of approximately 44.5 billion won ($31 million) in Solana-based assets on November 27. Upbit Strengthens Security After Second November 27 Breach According to operator Dunamu, Upbit currently maintains 98.33% of customer digital assets in cold storage as of late October, with only 1.67% held in hot wallets. The exchange stated it has completed a full wallet infrastructure overhaul and aims to reduce hot wallet holdings to below 1% in the coming months. Dunamu emphasized that customer asset protection remains Upbit’s top priority, with all breach-related losses covered by the company’s reserves. Sponsored Sponsored The breach marked Upbit’s second major hack on the same date six years ago. In 2019, North Korean hacking groups Lazarus and Andariel stole 342,000 ETH from the exchange’s hot wallet. This time, attackers drained 24 different Solana network tokens in just 54 minutes during the early morning hours. Under South Korea’s Virtual Asset User Protection Act, exchanges must store at least 80% of customer assets in cold wallets. Upbit significantly exceeds this threshold and maintains the lowest hot wallet ratio among domestic exchanges. Data released by lawmaker Huh Young showed that other Korean exchanges were operating with cold wallet ratios of 82% to 90% as of June. Upbit Outpaces Global Industry Standards Upbit’s security metrics compare favorably with those of major global exchanges. Coinbase stores approximately 98% of customer funds in cold storage, while Kraken maintains 95-97% of its funds offline. OKX, Gate.io, and MEXC each keep around 95% of their funds in cold wallets. Binance and Bybit have not disclosed specific ratios but emphasize that the majority of…

The post Tidal Trust Files For ‘Bitcoin AfterDark ETF’, Could Off-Hours Trading Boost Returns? appeared on BitcoinEthereumNews.com. Tidal Trust has filed for the first Bitcoin AfterDark ETF with the U.S. SEC. The product looks to capture overnight price movements of the token. What Is the Bitcoin AfterDark ETF? Tidal Trust has filed with the SEC for its proposed Bitcoin AfterDark ETF product. It is an ETF that would hold the coin only during non-trading hours in the United States. This filing also seeks permission for two other BTC-linked products managed with Nicholas Wealth Management. Source: SEC According to the registration documents, the ETF would buy Bitcoin at the close of U.S. markets and then sell the position the following morning upon the reopening of trading. In other words, it will effectively hold BTC only over the night “The fund trades those instruments during U.S. overnight hours and closes them out shortly after the U.S. market opens each trading day,” the filing said. During the day, the fund’s assets switch to U.S. Treasuries, money-market funds, and similar cash instruments. That means even when the fund has 100% notional exposure to Bitcoin overnight, a substantial portion of its capital may still sit in Treasuries during the day. Eric Balchunas, senior ETF analyst cited earlier research and said, “most of Bitcoin’s gains historically occur outside U.S. market hours.” If those patterns persist, the Bitcoin AfterDark ETF token will outperform more traditional spot BTC products, he said. Source: X Balchunas added that the effect may be partly driven by positioning in existing Bitcoin ETFs and related derivatives activity. The SEC has of late taken an increasingly more accommodating approach toward crypto-related ETFs. This September, for instance, REX Shares launched the first Ethereum Staking ETF. It represented direct ETH exposure and paid out on-chain staking rewards.  Also on Tuesday, BlackRock filed an application for an iShares Staked Ethereum ETF. The filing states…
