When people talk about the price of Bitcoin, they are referring to the current price at which Bitcoin is changing hands. Since Bitcoin is a purely speculative asset, this price is determined by how little sellers are willing to charge and how much buyers are willing to pay. Even then, the price of Bitcoin can vary across exchanges like Coinbase and Binance or currencies because of market inefficiencies
Bitcoin (BTC) is the world’s first decentralized digital currency and payment system and is by far the most known and valuable cryptocurrency. It was created in 2009 by an anonymous person or group called Satoshi Nakamoto. Bitcoin enables transactions to be sent peer-to-peer without passing through a central authority. The transactions are recorded on a decentralized public ledger called the blockchain and each payment acquires a small transaction fee to cover the cost of the network. The total supply of Bitcoin is 21 million and it’s smallest unit of bitcoin is called a Satoshi, it’s a hundred millionth of a bitcoin – 0.00000001 BTC. The creation of Bitcoin’s is happening through mining. Miners have the task to validate transactions and keep the network secure. Their efforts are rewarded by new minted Bitcoins and transactions fees. Bitcoin can be exchanged for fiat or other cryptocurrencies, products and services. Over 100,000 merchants and vendors accepts bitcoin as a payment.
“The arguments have devolved over three or four years of bitter debate, the principles are real and they are important to preserve, but a lot of the drama has nothing to do with principles anymore. A lot of this debate is now more about hurt feelings. It’s about bruised egos. It’s about things that were said that can’t be unsaid, insults that were exchanged, and personalities and ego.”
Bitcoin is the world’s first virtual digital currency underpinned by a completely decentralized blockchain technology also known as the Distributed Ledger Technology (DLT). Bitcoin was first created in 2009 by an anonymous identity of Satoshi Nakamoto. Bitcoin allows for peer-to-peer transactions and is completely free of any third-party involvement like financial institutions or central banks. The Bitcoin’s blockchain network maintains a history of all the transactions made and facilitates instant funds transfer with minimal transaction fees required to cover the cost of network operation. The total supply of Bitcoin is fixed at 21 million coins and its smallest fractional unit is called as Satoshi. Each Satoshi is a hundred millionth of a Bitcoin which means 100,000,000 Santoshi = 1 BTC. Bitcoins are generated by a process known as ‘mining’ which involves solving of complex mathematical algorithms. The miners involved in the mining process look after the Bitcoin network security and validate each transactions taking place on the network. Bitcoin can be exchanged with other digital currencies or fiat currencies. Bitcoin is used as a means of payment by over 100,000 vendors and merchants.
There are two factions of bitcoin supporters, that support large blocks or small blocks. The Bitcoin Cash faction favors the use of its currency as a medium of exchange for commerce while the Bitcoin-supporting faction view bitcoin's primary use as that of a store of value. Some Bitcoin supporters like to call Bitcoin Cash “Bcash,” “Btrash,” or simply a scam, while Bitcoin Cash advocates insist that their implementation is the pure form of Bitcoin.
If you have the required hardware, you can mine bitcoin even if you are not a miner. There are different ways one can mine bitcoin such as cloud mining, mining pool, etc. For cloud mining, all you need to do is to connect to the datacenter and start mining. The good thing about this is that you can mine from anywhere and you don’t need a physical hardware to mine.

When she persists, he confides in her that he had made a commitment to his late widowed seamstress mother that he will wed any woman who will manage to survive on just Rs.500/-, for 90 days. She finds out that this sum is equivalent to just 35 shillings but readily accepts this challenge. She also informs him that her late father had also imposed a condition that she must wed a male who will turn £500 into £15000 within the same period. Epifania then finds employment with an Italian firm, ends up re-organizing, and turning up the firm's profits. At the end of 90 days, she goes to meet Kabir and discovers that he has not only given all the money away but also has no interest whatsoever in marrying her.
而 Jamal 是个不折不扣的理想主义者。他善良而执着，对 Latika 一直不肯放弃。 Salim 在火车上数钱的时候， Jamal 脑子里想的都是 Latika ，兄弟俩的人生观一目了然。演员 Dev Patel 现实中也是只有 18 岁，有人说 Jamal 看起来太单薄，跳起舞来都是长手长脚的。但是这有什么关系呢？外型虽然薄弱，意志却无比坚强。 开头被拷打时，胖警察报告审了他一夜，除了名字什么都没问出来——“ He’s a tough guy.” 他的长官说“ What the hell can a slumdog possibly know” 的时候，背后被电晕的 Jamal 吐了一口血：“ The answers.” 这个镜头，我印象非常深刻。 18 岁的 Jamal Malik 因为这种坚强而显得格外性感。如果说这部电影是个童话，那也一定是因为 Jamal 这种近似不可能的执着和坚持，而不是男女主人公的离奇爱情故事。选不出“ Truth Alone Triumphs.” 的 Jamal ，他的人生故事却是这句话的完美诠释。 如果 Salim 是那个社会的代表型人物， Jamal 就是印度人民的精神象征，这就解释了为什么 Jamal 的天真善良和理想主义是理所当然的，也解释了为什么 Jamal 赢大奖后人们都为他兴奋欢呼。
