受贸易关税影响，任天堂Switch 2美国预购延期
任天堂原定于2025年4月9日开启Switch 2的美国地区预购，但由于美国总统特朗普近日宣布对大多数贸易伙伴实施大规模关税，导致市场不确定性增加，任天堂决定无限期推迟预购启动时间。
任天堂在一份声明中表示：“为了评估关税可能带来的影响以及不断变化的市场环境，美国地区的Switch 2预购将不会按计划在4月9日启动。我们将于稍后公布新的时间表。”不过，Switch 2仍计划于2025年6月5日正式上市。

Bitcoin mining is the process of adding new transactions to the Bitcoin blockchain. It’s a tough job. People who choose to mine Bitcoin use a process called proof of work, deploying computers in a race to solve mathematical puzzles that verify transactions.To entice miners to keep racing to solve the puzzles and support the overall system, the Bitcoin code rewards miners with new Bitcoins. “This is how new coins are created” and new transactions are added to the blockchain, says Okoro.
Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
