[00:00.100] | From VOA Learning English, |
[00:02.620] | this is the Economics Report. |
[00:05.670] | Many people who want to buy goods, pay for services, |
[00:10.530] | or send money anywhere in the world are using Bitcoin. |
[00:15.430] | They do not have to use banks, credit cards |
[00:19.150] | or other financial services |
[00:21.650] | when they use the electronic currency. |
[00:25.280] | Unlike national currency, |
[00:28.530] | Bitcoin is not issued by governments. |
[00:31.990] | Bitcoin is electronically protected or encrypted. |
[00:37.960] | It is bought, sold and transferred |
[00:41.970] | like other currencies through trading companies. |
[00:46.530] | Transfers happen without governments being involved |
[00:51.780] | or regulating the currency. |
[00:54.590] | Jerry Brito is a technology policy analyst |
[00:59.800] | at George Mason University. |
[01:02.420] | He says Bitcoin is the world's first, |
[01:06.180] | true digital currency, that is not controlled by anyone. |
[01:11.780] | "Bitcoin basically solved a computer science problem that, |
[01:17.240] | for the first time, allows just two people to transact online, |
[01:21.640] | so it's decentralized. There's no Bitcoin company, |
[01:23.990] | there’s no government, it's kind of like email." |
[01:27.210] | However, the very things that people like about Bitcoin, |
[01:32.210] | are also what criminals like about it. |
[01:35.820] | They want to move money from place to place secretly, |
[01:40.920] | without governments knowing about it. |
[01:43.890] | Law enforcement agencies in the United States |
[01:48.440] | recently closed an online market that used Bitcoin. |
[01:53.750] | Marco Santori is the chairman of the Bitcoin Foundation's |
[01:58.900] | Regulatory Affairs Committee. |
[02:01.600] | He notes that all Bitcoin transactions |
[02:06.010] | can be seen by all other computers, |
[02:09.170] | and he says they believe |
[02:11.570] | that no one regulates the currency is not true. |
[02:15.570] | "Bitcoin is in fact heavily regulated. |
[02:18.190] | It is very heavily regulated. |
[02:20.200] | Those who exchange Bitcoins for other digital currencies |
[02:23.860] | or exchange Bitcoins for dollars are money transmitters |
[02:27.480] | under the Bank Secrecy Act," said Santori. |
[02:29.130] | The amount of Bitcoins in the system |
[02:32.720] | must always be counted and tracked. |
[02:35.690] | Users' computers that watch and approve Bitcoin sales |
[02:41.340] | and purchases are given new Bitcoins. |
[02:45.600] | Mr Brito says this is how more money is added to the system. |
[02:51.820] | "Every 10 minutes, |
[02:52.970] | there are about 25.5 Bitcoins introduced into the economy, |
[02:56.940] | and it is given to one of the miners, |
[02:59.800] | kind of at random as it were, |
[03:02.340] | who are contributing the computer capacity," said Brito. |
[03:05.050] | The United States, Germany, |
[03:07.700] | and many other governments accept the use of Bitcoins, |
[03:11.810] | but some officials have called for stronger regulations |
[03:16.020] | on the electronic currency. |
[03:18.320] | China recently banned its banks, |
[03:22.000] | but not businesses, from trading in Bitcoin. |
[03:26.660] | Since its beginning in 2009, |
[03:30.910] | the value of a Bitcoin has increased from just a few pennies |
[03:36.030] | to hundreds of American dollars. |
[03:39.130] | And that's the VOA Learning English Economics Report. |
