Good Morning, Asia. Here's what's making news in the markets: Welcome to Asia Morning Briefing, a daily summary of top stories during U.S. hours and an overview of market moves and analysis. For a detailed overview of U.S. markets, see CoinDesk's Crypto Daybook Americas. Rest in Peace, Coinbase Wallet. No, the app itself isn't going away, but it is getting a new name. On its X profile , its name is crossed out and replaced with a 'TBA' and a few question marks. "There’s plenty of speculation about what it means, but I’m leaning toward 'The Base App.' That would fit the idea of Base unveiling a range of in-app experiences directly inside its wallet," Bradley Park, a Seoul-based analyst with DNTV Research, told CoinDesk in an interview. Base Creator Jesse Pollak was tapped to lead Coinbase's Wallet team last October , which lends credence to Park's theory. In an interview on the sidelines of Devcon in Bangkok last year, Pollak pla...

Embora os mercados tenham se estabilizado um pouco desde segunda-feira, o sentimento continua frágil em meio a uma nova rodada de tarifas emitidas por Donald Trump e outra semana de fluxos instáveis de ETFs. O BTC foi negociado perto de US$ 114.200 nas horas da tarde asiáticas de terça-feira, permanecendo estável no dia, mas ainda abaixo da faixa-chave de US$ 115.000 – US$ 118.000 que atuou como suporte de curto prazo nas últimas duas semanas.

Bitcoin Struggles to Hold $115K; Solana, Dogecoin Show Relative Strength as Risk-Off Sentiment Lingers

-
Bitcoin (BTC0 remains stuck below $115,000 after a sharp weekend drop that erased nearly $6,000 from local highs and triggered over $1 billion in liquidations across leveraged long positions. While markets have stabilized somewhat since Monday, sentiment remains fragile amid a fresh round of Donald Trump-issued tariffs and another week of choppy ETF flows. BTC traded near $114,200 in the Asian afternoon hours on Tuesday, remaining flat on the day but still below the key $115,000 – $118,000 range that had acted as short-term support over the past two weeks. Ether (ETH) fared slightly better, recovering toward $3,650 after dipping under $3,550 over the weekend, supported by sustained institutional interest and resilient flows. “Although Bitcoin has not managed to regain ground past $115,000, Ethereum has nearly recovered this week’s dip,” said Nick Ruck, director at LVRG Research, in a note to CoinDesk. “Treasury strategies, IPOs, and the hunt for the next MicroStrategy are fueling ...
