From VOA Learning English, this is the Economics Report.
Many people who want to buy goods, pay for services, or send money anywhere in the world are using Bitcoin. They do not have to use banks, credit cards or other financial services when they use the electronic currency.
Unlike national currency, Bitcoin is not issued by governments. Bitcoin is electronically protected or encrypted. It is bought, sold and transferred like other currencies through trading companies. Transfers happen without governments being involved or regulating the currency.
A pile of bitcoin tokens - a retro- futuristic kind of prepaid currency that made its debut four years ago - are shown, April 2013.
Jerry Brito is a technology policy analyst at George Mason University. He says Bitcoin is the world's first, true digital currency, that is not controlled by anyone.
"Bitcoin basically solved a computer science problem that, for the first time, allows just two people to transact online, so it's decentralized. There's no Bitcoin company, there's no government, it's kind of like email."
However, the very things that people like about Bitcoin, are also what criminals like about it. They want to move money from place to place secretly, without governments knowing about it. Law enforcement agencies in the United States recently closed an online market that used Bitcoin.
Marco Santori is the chairman of the Bitcoin Foundation's Regulatory Affairs Committee. He notes that all Bitcoin transactions can be seen by all other computers, and he says they believe that no one regulates the currency is not true.
"Bitcoin is in fact heavily regulated. It is very heavily regulated. Those who exchange Bitcoins for other digital currencies or exchange Bitcoins for dollars are money transmitters under the Bank Secrecy Act," said Santori.
The amount of Bitcoins in the system must always be counted and tracked. Users' computers that watch and approve Bitcoin sales and purchases are given new Bitcoins. Mr Brito says this is how more money is added to the system.
"Every 10 minutes, there are about 25.5 Bitcoins introduced into the economy, and it is given to one of the miners, kind of at random as it were, who are contributing the computer capacity," said Brito.
The United States, Germany, and many other governments accept the use of Bitcoins, but some officials have called for stronger regulations on the electronic currency. China recently banned its banks, but not businesses, from trading in Bitcoin.
Since its beginning in 2009, the value of a Bitcoin has increased from just a few pennies to hundreds of American dollars.

这里是美国之音慢速英语经济报道。
很多想购买商品、支付服务或在全世界任何地方转账的人都在使用比特币，使用这种电子货币时，他们并不需要使用银行、信用卡或其他金融服务。
与国家货币不同，比特币不是政府发行的，比特币得到电子保护或加密，像其他货币那样通过交易公司购买、售出和转让。转让不需要政府的参与，也不需要监管部门的监管。
杰里·布里托是乔治梅森大学的技术政策分析家，他说比特币是全世界第一个真正的电子货币，不受任何人控制。
“比特币基本上解决了一个电脑科学难题，即首次允许两个人进行网络交易，所以是去中心化的。不存在比特币公司，没有政府，有点像电子邮件。”
然而，人们喜欢比特币的原因也是犯罪喜欢的原因，他们希望在政府不知情的情况下秘密地转移资金。美国执法机构最近关闭了使用比特币的在线市场。
马可·桑托利是比特币基金监管事务委员会主席，他指出，所有的比特币交易都能被其他电脑看到，他说他认为没有人监管比特币的说法是不对的。
“比特币事实上受到严密的监督，用比特币交换其他电子货币或美元的货币交易者都受到银行保密法的约束。”
系统内的比特币数量必须一致得到清点和跟踪，监视并批准比特币销售和购买的用户电脑会得到新的比特币，布里托说更多资金就是这样进入系统的。
“每10分钟就有25.5个比特币进入经济，被随机发给为电脑容量做贡献的矿工。”
美国、德国和许多其他国家的政府最近都接受比特币的使用，但有的官员呼吁对这种电子货币实施更有力的监管。中国最近禁止银行交易比特币，但不禁止公司交易。
自从2009年比特币诞生以来，比特币的价值已经从几美分上涨到数百美元。
