比特币到底是什么？为什么很多投资者大量购入？

比特币是一种去中心化的电子货币，它的发明者是一位匿名的程序员Satoshi Nakamoto，于2009年发布。它是一种基于密码学的货币，使用全球分布式数据库来确保安全性。

Bitcoin is a decentralised electronic currency, invented by Satoshi Nakamoto, an anonymous programmer, released in 2009. It is a cryptographic-based currency that uses a global distributed database to ensure security.

比特币不像传统货币，它不是由政府或中央银行发行，而是由网络中的用户自发形成，它也不受任何国家或地区的监管。

Bitcoin, unlike a traditional currency, is not issued by the Government or the Central Bank, it is created spontaneously by users in the network, and it is not regulated by any country or region.

比特币的交易是通过区块链技术实现的，它是一种分布式账本技术，它可以记录所有比特币的交易历史，并且每笔交易都是不可篡改的。比特币交易是安全可靠的，因为比特币网络中的每一台计算机都可以检查交易的正确性，确保交易的安全性。

Bitcoin transactions are made through block chain technology, which is a distributed booking technology that records the history of all bitcoin transactions, and every transaction is undisguised. Bitcoin transactions are safe and reliable, because every computer in the Bitcoin network can check the correctness of the transaction and ensure the security of the transaction.

比特币的优势在于它具有去中心化的特点，它不受任何一个国家或地区的政治影响，它可以在全球范围内进行交易，不受时区、货币和法律的限制。比特币交易的费用也很低，比特币的交易手续费比其他货币低得多，使得比特币的交易成本更低。

The advantage of Bitcoin is that it is decentralized, free from any national or regional political influence, and that it can be traded on a global scale, free of time zones, currency, and legal constraints. Bitcoin transactions are also low, and bitcoins transactions are much lower than other currencies, making bitcoins more costly.

比特币的缺点在于它的价格波动较大，比特币的价格受到全球政治和经济动荡的影响，可能随时发生剧烈变化，对投资者来说，投资比特币具有一定的风险。另外，比特币的使用仍然处于起步阶段，它的应用范围尚不够广泛，用户也不够多。

The disadvantage of Bitcoin is that its prices are highly volatile, subject to global political and economic turmoil, and are likely to change dramatically at any moment, with investment in bitcoin at some risk for investors. Moreover, the use of bitcoin is still in its initial stages, and its application is not widespread enough, nor does it have enough users.

总的来说，比特币是一种新兴的数字货币，它具有去中心化的特点，低交易成本，安全可靠，但由于价格波动较大，应用范围有限，所以投资比特币需要谨慎。

In general, Bitcoin is an emerging digital currency characterized by decentralisation, low transaction costs and security, but investment in bitcoin requires caution because of high price volatility and limited application.
