What is Bitcoin?
Bitcoin is the first decentralized digital currency.
Bitcoins are digital coins you can send through the Internet.
Compared to other alternatives, bitcoins have a number of advantages.
Bitcoins are transferred directly from person to person via the net
without going through a bank or clearinghouse.
This means that the fees are much lower,
you can use them in every country,
your account cannot be frozen
and there are no prerequisites or arbitrary limits.
Let's look at how it works.
Several currency exchanges exist where you can buy and sell bitcoins
for dollars, euros and more.
Your bitcoins are kept in your digital wallet on your computer or mobile device.
Sending bitcoins is as simple as sending an email
and you can purchase anything with Bitcoin.
The Bitcoin network is secured by individuals called miners.
Miners are rewarded newly generated bitcoins for verifying transactions.
After transactions are verified they are recorded in a transparent public ledger.
Bitcoin opens up a whole new platform for innovation.
The software is completely open source and anyone can review the code.
Bitcoin is changing finance the same way the web changed publishing.
When everyone has access to a global market, great ideas flourish!
Bitcoins are a great way for businesses to minimize transaction fees.
It doesn't cost anything to start accepting them and it's easy to setup.
There are no chargebacks and you'll get additional business from the Bitcoin economy.

影片簡介

小編還記得5月一知道 Wanna Cry 勒索病毒事件的時候,馬上飛奔到電腦身旁,先誠心祈禱再小心翼翼按下開機鍵...... 呼!幸好沒有中毒!新聞還說駭客要求用比特幣當贖金,小編真的是一頭霧水,到底什麼是比特幣呢,我們一起來看看!

1a number of0:09
a number of 的意思為「一些、若干」,後面必須接複數可數名詞,也可以在 number 前面加上 large,以 a large number of 表示「大量的」。
There are a number of churches in the city.
這個城市有一些教堂。

A large number of customers swamped into the store.
大量顧客湧入那間商店。


小編再介紹幾個 number 實用的用法給大家:

somebody's/something's days are numbered 某人/某物的壽命將盡、時日不多
It seems that my car's days are numbered, so I am going to buy a new one.
我的車看來是快壞了,所以我正準備購入新車。


do a number on somebody 傷害某人、對某人做不好/不公平的事
He did a number on Jane at work, which made her totally upset.
他在工作上傷害了 Jane,這使她非常難過。

3secure0:47
影片中 secure 是當動詞用,意思為「保衛、使安全」,而 secure 這個字除了有動詞和形容詞兩種詞性外,各自也包含了不同的意思,是個很常使用到的單字喔!

secure 當動詞用時,有「弄牢、關緊」的意思。也有「獲得」的意思,通常在這個「獲得」的過程中,是經歷了些許困難的。
The staff had secured all the windows in the store before the typhoon came.

secure 當形容詞用,有「牢固的、牢靠的」意思。也有「安全的、無危險的」意思,通常用來指物品或是環境。

別擔心!這個梯子很牢固的。

The reason of hiring a guard is to ensure that my house is secure against burglary.

secure 也可以用來形容人的感受,有「安心的」意思。

4flourish1:16
影片中 "great ideas flourish",是指點子「迸發」,有「蓬勃發展、興盛」的意思,可用於商業、現象、創意等;用於植物上時,則有「茂盛生長」的意思。形容詞 flourishing 意思與動詞相同,用來形容某事物是「繁榮的、蓬勃發展的」。
The real estate business has been flourishing in recent years.
近年來房地產事業蓬勃發展。

Flowers flourish in spring.
花朵在春天時盛開。


flourish 的同義字有:
用於指「(商業)繁榮、蓬勃發展」時,flourish 可用 thriveprosper 替換。
用於指「(植物)茂盛生長」時,flourish 則可用 thrive 替換。

最近比特幣真的很紅,恭喜大家都跟上了潮流,對比特幣有基本的認識了,小編也祝大家的電腦健康平安,百毒不侵><
