From the beginning of 2009, 1300 bitcoin 1 US dollar, and now a bitcoin sells more than 6,000 US dollars, soaring nearly 7.8 million times, becoming the only thing in recent years that is higher than house prices. For a time, cryptocurrency was again hyped by investors and miners, calling it the hope of future currency. Only when it gets more cryptocurrency can it guarantee that it will not fall on the starting line. The madness of mining has been going on for many years. More and more people are pouring into this industry.

However, in the short term, the output and appreciation rate of cryptocurrency has greatly exceeded the demand of consumer circulation. The fast appreciation is not destined to replace the long-term mainstream currency. Otherwise, the gain of waiting for appreciation is much greater than investment and labor, and no one consumes. Money can't be circulated, and finally the cryptocurrency will return to its essence, becoming a string of meaningless code in the hands.

At present, some companies are trying to use digital currency. This means that digital currencies are making some progress in traditional payment scenarios. Despite the low demand for payments using digital currency, people are also preparing for new market trends and forms of trading.

Of course, it may be too early to talk about the future of digital currency as a means of payment. As digital currencies become more regulated, market participants will slowly learn about digital currencies and try to work with them.

People are worried that cryptocurrencies may be used for terrorist activities, but terrorists have failed many bitcoin financing attempts, and cash is still much more useful for terrorists. However, despite the fact that terrorist organizations may not have achieved much success in cryptocurrency, there are reports that several white supremacist groups around the world are gaining success in encryption fundraising and payment.

The relationship between artificial intelligence and blockchain is like the relationship between computers and the Internet. Computers provide production tools for the Internet, and the Internet realizes information interconnection for computers. Artificial intelligence will solve the autonomy, efficiency and energy saving of blockchains. And the intelligence and other aspects of the problem, and the blockchain will use the islanded, fragmented artificial intelligence to achieve common intelligence in a shared way, the former is the tool, the latter is the purpose.

If emerging markets recover before the end of this year, the development trend of the global financial industry is moving toward the depreciation of the US dollar. Bitcoin prices are likely to soar in 2019, and may even exceed $20,000 at the end of 2017.

The total amount of Bitcoin is fixed and is a deflationary currency. If Bitcoin replaces the fiat currency, it will immediately lead to a deflationary economy. In other words, your wages will fall after a period of time, because bitcoin is rising; the GDP of the country that is denominated in bitcoin will never rise, and the state will increase taxes to make up the coinage tax. So I do not think that Bitcoin will replace fiat currency.

Bitcoin has value because it is useful as a form of currency. Bitcoin has the mathematical properties of money (persistence, portability, interchangeability, scarcity, severability, and legibility) rather than relying on physical characteristics (such as gold and silver) or the trust of the central authority ( Such as legal tender). In short, bitcoin is supported by mathematics. With these characteristics, what is needed for a monetary form to have value is trust and use. For Bitcoin, this can be seen in its growing base of users, merchants and start-ups. Like all currencies, the value of Bitcoin comes directly from people who are willing to accept it as a means of payment, and this is the only source.

The strong performance of emerging market-based assets and ETFs is likely to lead to an increase in bitcoin prices, as the correlation between the two can be traced back to the beginning of 2017.

The relationship between bitcoin and energy has always been complicated. The claim about excessive energy consumption may be a bit exaggerated. At least there is not enough speech to prove that global warming has anything to do with mining. But the development of virtual currency needs to move towards sustainability, encourage new innovations that reduce emissions, and inspire some people to develop carbon-neutral currencies.

This kind of awareness must be reflected in practical applications. For example, a baseball player in Japan initiated a petition, hoping to use XRP as the official digital currency of the 2020 Tokyo Olympics. Once the petition is approved, the acceptance and adoption of XRP will be greatly improved, and people will have a stronger awareness of the virtual currency. bitcoin is also the same, it must be used in practice, so it is a crucial step for bitcoin to replace fiat money and become a new payment method.

Whenever bitcoin prices rise, more new users will join the Bitcoin ecosystem, and more people will use Bitcoin every day. Simply put, if Bitcoin networks can't handle increasing transaction flows by increasing throughput, Bitcoin will be difficult to retain users for a long time.

What came into my mind first is stock when I think of currency. Because both of them are investment products and the value of both depends on the next buyer. But the risk of investing in
cryptocurrency is much higher than stock investment.

Bitcoin is not just a coin, but a consensus network that has led to a new payment system and a fully digital currency. It is the first decentralized peer-to-peer payment network that is controlled by its users without the need for a central authority or intermediary. From the user's point of view, Bitcoin is much like the cash of the Internet.

Because bitcoin (and stability as a means of storing value, whether it's worth $10, or $100, or $1000) won't go away. Bitcoin has always been a stable means of value storage

The 2008 global financial crisis, the Greek debt crisis, and the growing financial needs of a growing number of national economies have raised questions about the central bank that monopolizes the issuance of currency. Perhaps considering these issues, the International Monetary Fund (IMF) recently published an article on cryptocurrency, which unexpectedly called cryptocurrency or would become a "future currency."
So, is it possible for cryptocurrencies to eventually replace fiat money and the central bank. But teare are also some questions about this issue, including:
1. Will this shift reduce the market demand for central bank currency?
2. Will this change affect the ability of the central bank to control monetary policy and interbank lending rates?
3. Will this change allow the central bank to start designing interest rates for encrypted assets as well?

I think the central bank will not be replaced in the early years before these issues are confirmed.

Any investment has certain risks, so make sure that your investment amount is within your acceptable range.

With the continuous influx of new miners, the difficulty of computing will gradually increase, and the computing power required to mine up Bitcoin will increase greatly. The increase in computing power means an increase in cost. The output of Bitcoin is getting less and less, the computing power is always increasing, and the balance of pay and return is slowly tilting.

I absolutely agree with you, and the speculators should be regulated.
Speculators became the dominant group behind most Bitcoin transactions and went beyond criminals and drug dealers. Five years ago, Infante's analysis of blockchain data showed that illegal activities accounted for about 90% of all bitcoin transactions. However, this trend has completely changed, with only 10% of transactions currently blamed on criminals, and speculators are currently the main drivers of the market.

Make a profit, invest in moderation. Evaluate your financial situation, and invest moderately without affecting your normal life. Imagine if you woke up one morning and found that your investment situation was a mess, the losses make you unable to pay the bill for the next month? If so, then you have invested too much. There is no doubt that investment failure will always hurt, but if you invest properly, even if the worst happens, it will not be a devastating blow to you.

Cryptocurrency payments do protect the interests of users, such as:
Protect consumer privacy
Promote capital flows and achieve truly borderless business
Reduce "pending transactions" queues
Cut high transaction costs

But many improvements are needed before users can adopt cryptocurrency payments in large-scale.
Price fluctuations: cryptocurrency price fluctuations make it difficult to maintain equilibrium.
Security: Even the most secure cryptocurrency wallet at the moment can be hacked. How to ensure the security of user assets is also the key to the healthy development of the cryptocurrency market.
