哥伦比亚大学开始对示威学生进行停学处理后，一批学生占领哈密尔顿大楼，校方声称将开除占领大楼的学生。在历史上哈密尔顿大楼多次被示威学生占领。1968年反战学生占领该楼一周，校方叫来警察清场，抓捕700多名学生、打伤100多名学生，但学校答应了示威学生的所有诉求，包括停止与军方合作、取消在哈莱姆的公园建体育馆、赦免所有示威学生、校长和教务长辞职。1985年学生占领该大楼三周，校方答应学生诉求，剥离对南非的投资。这些都成为学校光荣历史的一部分。

How Does Bitcoin Mining Work?

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.
