#Bitcoin❗ スティーク ‘n シェイク、ビットコインの受け入れで知られるアメリカのファーストフードチェーンが、エルサルバドルへの進出を発表しました。同社は、ビットコイン歴史的イベントに参加した後、「ビットコイン国」に参加することを誇りに思うと述べました。スティーク ‘n シェイクは5月からBTCでの支払いを受け入れ始め、COOのダン・エドワーズは、長期的な目標は世界中のすべての店舗でビットコインでの支払いを可能にすることだと述べています。
10月、同社は支払いオプションとしてイーサを追加することについてフォロワーに調査を行いましたが、ビットコイン専用の支持者からの反発によりスティーク ‘n シェイクはそのアイデアを撤回しました。この短い論争にもかかわらず、同チェーンは第3四半期の同店舗売上が15%増加し、マクドナルドやスターバックスなどの主要な競合を上回り、ファーストフード業界での地位を強化しました。
Cryptocurrency began as a response to the need for decentralized digital money — money that doesn’t rely on banks, governments, or any central authority to operate. The history of cryptocurrency officially starts in 2009, when Bitcoin, the first-ever cryptocurrency, was launched. Its creator, known by the pseudonym Satoshi Nakamoto, introduced a completely new financial concept that marked the beginning of a global digital revolution. Bitcoin was created to solve several key problems found in traditional financial systems. The most important goal was to create a form of money that is decentralized, meaning no bank or government could control it. Another issue it aimed to solve was the double-spending problem, where digital money could be copied or used twice. Blockchain technology solved this by recording all transactions securely on a public ledger. Cryptocurrency also emerged to reduce transaction costs and delays commonly seen in the banking system. With crypto, people can send money across borders quickly and cheaply. It also provides financial independence by giving individuals full control over their own funds without needing permission from any institution. The timing of Bitcoin’s launch, right after the 2008 financial crisis, shows it was also a response to the loss of trust in traditional banking. Before Bitcoin, several early concepts of digital money existed in the 1990s, such as DigiCash, but they failed because they were still centralized. The real breakthrough came in 2008 when Satoshi Nakamoto published the Bitcoin whitepaper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” In 2009, the first Bitcoin block, known as the Genesis Block, was mined, marking the official start of cryptocurrency. Later, in 2015, Ethereum expanded the industry further by introducing smart contracts, which enabled a wide range of new applications and innovations in the crypto world.
