The most valuable virtual currency for investment
bitcoin (bitcoin)
as the wind vane of virtual currency, its position in the coin circle is recognized. It is no exaggeration to say that the rise and fall of bitcoin affect the nerves of investors. For example, in the virtual currency trading in the domain Kingdom, investors choose to be bullish or bearish, and they can make profits after maturity. Virtual currency is not only a currency, but also a symbol of virtual currency
Ethereum is regarded as the symbolic currency in the era of blockchain 2.0. The concept of public chain created by Ethereum is no less important than that of windows in the operating system, and its market value is second only to bitcoin. Ethernet currency is widely used in many cryptocurrency markets<
ripple
ripple is a kind of virtual currency. There are many old players who know ripple, but they are a little strange to novices. Since its founder Jed launched, reborn coin has many fans in China, and also has great influence in Europe, the United States and other regions
Factom
is one of the most popular cryptocurrency investment lists. Factom currently ranks 79 on the cryptocurrency list, with a market value of $60927718 and a current price of $6.48, which means that it is likely to become a top big currency in terms of market value
don't invest in counterfeit currencies that are hot and hot for huge profits. Only a good currency can really help investors achieve their profit goals.
Bitcoin can still be invested. In addition, Phoenix coin is a good variety. You can have a try
now that we see the soaring price of bitcoin, which has broken through the sky, we are afraid to invest any more
in fact, this idea is very wrong. If we see the unique characteristics of bitcoin, we should understand that it is not too late to invest
we can no longer buy many bitcoins for one or two hundred yuan as before
but even if the bitcoin is worth $10000, we can still invest it, but the cost is relatively high
nowadays, many of bitcoin are in the hands of retail investors rather than some institutions, and the cost of acquiring bitcoin for these retail investors is relatively low, so they will not sell it too soon, and they may get it forever
such an approach will make the price of bitcoin continue to rise, so the investment value is still very considerable
now a new kind of Phoenix coin is also good, which is the same as the development of bitcoin, and also has offline trading channels
the price has risen from the initial $0.5 to $0.74, with a 50% return, which is amazing
Background: the financial application of blockchain technology brings high investment value
2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles
1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:
in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost
2. Why can blockchain solve the above pain points:
blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs
3. The application of blockchain technology in the financial field mainly includes the following aspects:
among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits
Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost③ digital bills
④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost
The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points
in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it
Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall) In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreementbitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain
based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network
2. Master node network
the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

the high housing prices destroyed the post-80s and post-90s
and then the world came back. Today's virtual currency
the post-80s also pulled back a round. Whether it is worth buying is not to see whether its current price is high or low
but to see whether it has value in the future and whether it will be useful for everyone's life There must be only a few bitcoins in total.
bitcoin has become a kind of value preservation proct corresponding to gold
decentralized anonymity advantage
bitcoin comparable to gold
moreover, more and more businesses have accepted bitcoin transactions
some institutions have also accepted bitcoin donations, and bitcoin ATM has become a hot topic Put into use
the second is
Ethereum (ETH)
it can be said that it is an evolutionary version of bitcoin
bitcoin is gold, Ethereum is silver
Ethereum's technology can be applied to real world applications
JPMorgan Chase, Microsoft, etc. are all optimistic about Ethereum technology
In my opinion, the most stable return is the twoand the other multifarious currencies have gone up and down sharply. Ordinary people's hearts can't stand
at present, domestic users can buy through this website
transactions
it's not the price rise of the currency but the price rise of the currency through the bar The number of coins is rising
1. Look at technology
2. Look at the total amount
3. Look at the team
indivials don't look at the U.S. card currency and Yuan Bao currency, which have no technical advantages, but the virtual currency which has a rapid appreciation e to the positive actions of the team. Because there is no technical advantage, this currency can be hyped in a short time, but the long-term future is uncertain. Quarks are currently recommended.
