Bitcoin climbing flowering
Bitcoin isn't the only digital token currency, and its underlying blockchain isn't the only one out there. A rival blockchain is Ethereum, which has its own currency, Ether. Ethereum features 'smart contract' functionality for online contractual agreements.
One of the biggest problems with the world's existing financial system is its failure to achieve 'financial inclusion' — i. According to a study from the World Bank, around 39 percent of the world's population, including two billion adults, are 'unbanked' — they don't even have a bank account.
Bitcoin doesn't help the poor, Perrin says, because both of the main ways to obtain bitcoins are unaffordable to the poor. One way is to buy bitcoins through online 'bitcoin exchanges,' using real money. Will Bitcoin continue to rise in perceived value?
Will it cost more and more real money to buy a single Bitcoin in future? There's no reliable way to predict short-term Bitcoin price movements.
But there are reasons to suspect that in the long term, Bitcoin may lose most or all of its value. One reason is competition. There is a growing number of rival cryptocurrencies, some of which may be better-designed than Bitcoin. Is Bitcoin the new gold? Gold has been around for millennia. Bitcoin is, at this stage, a fad — and better-designed cryptocurrency systems that are actually useful in day-to-day transactions like grocery shopping may soon displace it.
Another risk to Bitcoin is regulation. Some countries have been trying to kill cryptocurrencies. Bitcoin takes flight again after overcoming roadblocks. Japan, by contrast, recently set up regulations for Bitcoin exchanges, which must apply for licenses to operate.
The new rules have recognized Bitcoin as a payment system. Nevertheless, the imprimatur of legality generated by Japan's regulation of Bitcoin appears to have caused many more people, especially in Japan, to view Bitcoin as a legitimate form of financial instrument, and to 'invest' in Bitcoins.
This has arguably been a key factor in causing the recent rapid rise in Bitcoin's price. But it doesn't really matter. You may never have used Bitcoin or other cryptocurrencies, but you're sure to have heard of the technology.
Andrew Miller tells DW why they could spark a backlash against our surrendering of private data. Has Bitcoin finally hit the ceiling many have predicted it would? But can the virtual currency sustain its record run amid increasing government regulation? He called the cryptocurrency a fraud and insisted it was destined to crumble like a house of cards one fine day.
Shrugging off fears of a possible price crash, the cryptocurrency has reached another record high. Despite climbing more than percent in a year, institutional investors remain skeptical about its prospects. Some of the world's biggest auto companies have teamed up with tech providers and startups to form a consortium aimed at developing automotive uses for blockchain, the database technology known from cryptocurrencies.
Apple Inc supplier Foxconn has agreed to manufacture a blockchain phone from startup Sirin Labs. The contract electronics maker's entry has heated up the race for a phone aimed at digital coin aficionados.

No one knows who created it. Bitcoin and other cryptocurrencies can be bought on online exchanges such as Coinbase , bitfinex , or Gemini. Bitcoin can also be bought at Bitcoin ATMs , at machines throughout the region, at a slightly higher cost. People also will sell Bitcoin privately after arranging meetings through Craigslist or Reddit.
Kevin Werbach , an expert in financial tech at the Wharton School, offers two explanations. The number of people trading cryptocurrencies on Coinbase has tripled this year to 13 million, according to Bespoke Investment Group.
Cryptocurrencies are also widely held in Japan, China and especially South Korea.
