PayPal Ethereum
Ethereum is likely to rise to 10000 in 2021
institutional investors and big capital are increasingly interested in cryptocurrency. The attention of all whales, and the attention of all the public, is focused on bitcoin. Since the global health and safety incident triggered the market crash in March 2020, the growth of eth has reached 1200%
while BTC only increased by 700%. Of course, in the context of bitcoin's record high price of 40000, Ethereum's rise to $1400 does not seem so impressive. In addition, the market value of eth is five times the trading volume of BTC market
extended information:
the increase of Ethereum is as follows:
the transaction volume recorded on Ethereum blockchain exceeds US $1 trillion. These figures exceed the transaction volume of payment giants such as PayPal, which is used by more than 350 million users and whose average transaction volume is generally less than $200 billion per quarter
each transaction will generate network fees paid by eth. Moreover, as the growth rate of the network is still very high, we can confidently expect the "bull market" trend of eth to continue. In any case, interest in cryptocurrency is growing, as are the number of active wallets, the number of transactions on the Internet, and the average size of transactions
although bitcoin still has great risks, after years of development, with the increase of its application population, application scenarios and application technology, no country or organization can completely eliminate it. If you can figure it out, it is likely that countries will generally accept bitcoin and embrace it
according to my personal judgment, bitcoin, after a period of continuous development, is likely to become a world currency in the future, which can play the role of electronic gold and become the target of the value of other sovereign currencies. From this perspective, bitcoin can be used as a means of asset preservation in the future when inflation is inevitable
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
on December 17, 2017, bitcoin reached an all-time high of $19850. On July 27, 2020, bitcoin broke through the $10000 mark again [2]<

from the transaction of things In 2008, the global financial crisis broke out. On November 1 of the same year, a person who called himself Satoshi Nakamoto published the white paper bitcoin: a peer-to-peer e-cash system [6] on the P2P foundation website, stating his new idea of e-money bitcoin came out. On January 3, 2009, bitcoin Genesis block was born
there are three bitcoins in total
compared with legal tender, bitcoin does not have a centralized issuer, but is generated by the calculation of network nodes. Anyone can participate in the manufacture of bitcoin, and it can circulate all over the world. It can be bought and sold on any computer connected to the Internet. No matter where they are, anyone can dig, buy, sell or receive bitcoin, And in the transaction process, foreigners can not identify the user's identity information. On January 5, 2009, bitcoin, which is not controlled by the central bank and any financial institutions, was born. Bitcoin is a kind of digital currency, which is composed of a series of complex codes generated by computer. The new bitcoin is made by preset program
whenever bitcoin comes into the view of mainstream media, mainstream media always ask some mainstream economists to analyze bitcoin. Earlier, these analyses always focused on whether bitcoin was a scam. Now the analysis is always focused on whether bitcoin can become the mainstream currency in the future. The focus of the debate is often on the deflationary nature of bitcoin[ 7]
many bitcoin players are attracted by the fact that bitcoin can not be added at will. Contrary to the attitude of bitcoin players, economists have a polarized attitude towards the fixed amount of 21 million bitcoin
Keynesian economists believe that the government should actively regulate the total amount of money, and use the tightness of monetary policy to timely fuel or brake the economy. As a result, they believe that bitcoin's fixed aggregate currency sacrifices its adjustability, and worse still, it will inevitably lead to deflation, thereby harming the overall economy. Austrian economists hold the opposite view. They think that the less the government intervenes in money, the better. The deflation caused by the fixed amount of money is not a big deal, even a sign of social progress
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer[ 6]
in 2009, when bitcoin was born, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25. When the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million[ 3]
bitcoin is a virtual currency with limited quantity, but it can be used to cash out: it can be converted into the currency of most countries. You can use bitcoin to buy some virtual items, such as clothes, hats, equipment, etc. in online games. As long as someone accepts it, you can also use bitcoin to buy real-life items
on February 25, 2014, the opening price of "bitcoin China" was 3562.41 yuan. By 4:40 p.m., the price had dropped to 3185 yuan, down more than 10%. According to the historical market data of the platform, on January 27, 2014, 1 bitcoin could be exchanged for 5032 yuan. This means that in less than a month on the platform, the price of bitcoin has dropped by 36.7%
on September 9 of the same year, the US e-commerce giant eBay announced that Braintree, its payment processing subsidiary, would start accepting bitcoin payments. The company has entered into a partnership with coinbase, a bitcoin trading platform, to begin to accept this relatively new means of payment
although the eBay market trading platform and paypal business do not accept bitcoin payment, Braintree customers such as airbnb, a travel house rental community, and Uber, a car rental service, will be able to start accepting this virtual currency. Braintree, whose main business is to provide payment processing software to enterprises, was acquired by eBay in 2013 for about $800 million
on the evening of January 22, 2017, fire coin, bitcoin China and okcoin announced on their respective official websites that in order to further curb speculation and prevent drastic price fluctuations, all platforms will start to collect transaction service fees from 12:00 noon on January 24, and the service fees will be charged at a fixed rate of 0.2% of the transaction amount, and the active transaction and passive transaction rates are the same[ 8] On May 5, according to the latest data of okcoin, the price of bitcoin has just set a new record, reaching a high of 9222 yuan by the time of publication. From 12:00 noon on January 24, China's three major bitcoin platforms officially began to collect transaction fees. On September 4, the central bank and other seven ministries and commissions announced that China banned virtual currency trading
on December 17 of the same year, bitcoin reached an all-time high of $19850
on November 25, 2018, bitcoin broke the $4000 mark and then stabilized at more than $3000[ 9] On November 19, cryptocurrency resumed its decline, and bitcoin fell to the $5000 mark for the first time since October 2017, e to BCH's hard bifurcations and the regulatory authorities' enhanced scrutiny of the initial token issue (ICO)[ 9] At 4:30 a.m. on November 21, the offer of bitcoin on the coinbase platform fell below $4100, a 13 month low
in April 2019, bitcoin broke the $5000 mark again, reaching a new high in the year[ 10] On May 12, bitcoin broke through $7000 for the first time in nearly eight months[ 11] On May 14, according to the offer of coin market cap, bitcoin stood at $8000, up 14.68% in 24 hours[ 12]
on June 22 of the same year, the price of bitcoin broke through the $10000 mark. Bitcoin prices fluctuated around 10200, rising nearly 7% in 24 hours[ 13] On June 26, the price of bitcoin broke through $12000, a 17 month high since January last year[ 14] In the morning of June 27, the price of bitcoin was close to $14000, reaching a new high of the year[ 15]
on February 10, 2020, bitcoin broke through $10000. According to trading data, bitcoin's price rose more than 3%, breaking the psychological limit of $10000 for the first time since October 26 last year[ 16]
on March 12, according to the data of bitstamp, the cryptocurrency trading platform, the lowest price of bitcoin dropped to US $5731 at 19:44[ 17]
on May 8, bitcoin broke through the $10000 mark, a new high since February[ 18]
from 8:00 a.m. on May 10, the unit price of bitcoin fell by thousands of dollars from $9500 in half an hour, with the lowest price falling below $8200 and the highest price difference exceeding $1400[ 19]
at 6 p.m. on July 26, bitcoin rose rapidly for a short time, reaching a maximum of 10150.15usdt, with a maximum increase of more than 4% within the day. This is the first time since June 2, 2020 that bitcoin has exceeded the $10000 level[ 2]
bitcoin has been "forked" more than 100 times in two years. How about those forked coins now

overseas mining rise: batch construction of us factories, On November 1, 2008, a self styled Satoshi Nakamoto published a bitcoin white paper, bitcoin: a peer-to-peer electronic cash system, on the P2P foundation website, stating his new idea of electronic money bitcoin came out
Wang yuexinyi, Professor of mathematics at Kyoto University, was born on January 3, 2009. Bitcoin uses distributed ledger to get rid of the constraints of third-party institutions, which Nakamoto calls "blockchain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money. Business is also extended on this network. Computers running this software are scrambling to solve the problem of irreversible code, which contains several business data. The first miner to deal with the problem will get a 50 bitcoin reward, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura
according to foreign media reports, computer scientist Ted Nelson released a video on the Internet on Sunday, saying that he has determined that the founder of bitcoin is Shinichi Mochizuki, a professor of mathematics at Kyoto University. The founders of bitcoin have always used

Now there are nearly 2000 kinds of cryptocurrencies in the world. Although it is useless to recognize all of them, we still need to know a little about the mainstream currencies in the world. Besides bitcoin, what is the mainstream cryptocurrency? At present, Ethernet is the second largest mainstream cryptocurrency after bitcoin. Ethereum is the name of currency used in Ethereum, which is also the abbreviation of blockchain 2.0 in Ethereum. In Ethereum virtual machine, Ethereum is used to pay the calculation fee. Through blockchain technology, everyone can build and use decentralized applications on the platform, which is the most widely used currency at present
bitcoin cash is a hard forked blockchain of bitcoin and forms a competitive relationship with bitcoin. Bitcoin cash is the best developed bitcoin fork currency. Many people think that it is a stock with only potential, and even can replace bitcoin. However, opponents believe that bitcoin cash is entirely in the interests of miners. Although the block size has been increased by 8 times, the isolated witness that will rece the mining income has been abandoned. Although changing the size of buildings can solve the congestion problem, many people think that it is a temporary solution rather than a permanent solution, which is of little significance to the development of blockchain technology
EOS is a blockchain architecture platform similar to the operating system developed by Daniel Larimer. This project aims to create a blockchain underlying platform with strong performance and low development threshold, just like Microsoft's windows. EOS even surpasses Ethereum's intelligent contract. The transaction speed is extremely fast. It can support millions of transactions per second, making Ethereum unable to catch up. EOS doesn't need to be mined, and adopts a more decentralized POS method. Many people think that EOS will be the star of tomorrow
MTL:
metal is a kind of digital currency based on blockchain technology, which is used to prove that users process payment confirmation and use MTL token for reward, similar to bitcoin. Metal has procts with a friendly user interface, such as venmo, square and paypal. As a payment tool, metal is suitable for bitcoin or other digital currencies. Although many small businesses in the world are more willing to accept cash, cashless is the future trend. Refusing to accept digital currency or credit card payment will lag behind this society. In short, metal only provides new digital currency services for enterprises. Digital currencies have common characteristics, especially in privacy protection. In order to bring digital payment into the real world, some traditional banking institutions are also using blockchain technology. Metal expects that this will save consumers 4% - 5% when they buy goods
XTL: Stellite is a modern, secure and decentralized open source cryptocurrency, driven by the community and providing user-friendly blockchain tools for daily devices. Stellite is the first cryptocurrency to connect IPFs and zeronet with blockchain, and all data is private<
ATL:
Atlant is a customizable decentralized system based on Ethereum Dao protocol. Token is the core of the platform, or ATL for short. ATL token is essentially the membership certificate of the Atlantic platform, which can give token owners the following rights: through the Atlantic platform, users can list all the properties of their assets. The platform allows owners and developers to token the property by creating custom smart contracts, so as to sell (part or all) the property or attract investment. The size of the underlying shares was initially proposed to be 7% of the assets, which will be decided by ATL token holders' vote. After successful crowdfunding, a portion of the tokens in escrow will be allocated pro rata to ATL token holders. After the completion of the P2P leasing transaction with the lessee, a small commission will be charged. These commissions are distributed to ATL token holders. The size of the fee is determined by the vote of ATL token holders. Through voting, we can decide various behaviors related to assets: platform listing decision, listing fee approval, law firm selection, management company selection (property token), rent approval, lease fee approval, etc. Within the framework of Atlant, through the rating system of arbitration institutions, coin holders can become arbitrators of arbitration solutions in P2P leasing services, and they can earn additional income in this way. The escrow funds held in trust by a third party are then allocated to the holders of ATL currency who are to execute the arbitration. Have influence within the platform. Token holders have the right to propose and vote, which can assist the further development of the platform, improve the efficiency of global real estate, and promote the global promotion and growth of Atlantic.
2, the common local payment tools for "toC" class Alipay, such as WeChat PayPal Po, etc., are applicable to businesses that have been popularized locally and are in favor of merchants in policy.
3. For international credit card collection, the common international cards are visa, masterc, JCB, AE, DC, etc. Payment companies get authorization from banks, and then provide the collection channel for foreign trade merchants to use. Foreign trade merchants can let users directly input the relevant information of international card on the web page or app, and then they can easily pay. It is convenient, fast, and has good experience, which is concive to the second payment

1. Ethereum: a better value accumulation target
for many years, accumulating bitcoin has been the main way to store the value of cryptocurrency. Investors use bitcoin as a sharp weapon against the economic crisis. However, institutional traders are now also interested in Ethereum
in the 2020 annual review report of coinbase, it is noted that institutional customers are more and more interested in Ethereum. The reason is related to how investors evaluate Ethereum ecosystem
first of all, it is the original currency of the network. Because Ethereum is a platform for many valuable projects, Ethereum has become a powerful trading currency in Ethereum ecosystem
Why are more and more institutional traders hoarding Ethereum
the report points out that the driving force for Ethereum holders to invest comes from: first, Ethereum's potential as a value store is constantly developing; 2、 Ethereum's status as a digital currency provides the basis for its network transactions<

2. Investment institutions such as coinbase and Gemini are optimistic about Ethereum and defi
Arthur Cheong, founder of definance capital and portfolio manager focusing on defi encryption fund, pointed out in a statement in coindesk, "I think bold investors will explore Ethereum and defi after studying bitcoin."
according to the data, some investment institutions such as coinbase and Gemini are incredibly bullish on Ethereum. In addition, more and more large investors are looking for different decentralized financing space
Why are more and more institutional traders hoarding Ethereum< However, deniss vinokourou, a digital asset investment manager, believes that "not everyone is satisfied with the risks associated with defi that still exist, but the rapid growth of active projects in Ethereum supports capital appreciation."
unlike bitcoin, Ethereum has many ways to retain investors and lock them in for a long time. After the release of eth2.0, Ethereum owners have made a lot of profits in long Ethereum

RSK smart contract is a smart contract platform based on bitcoin blockchain. RSK (rootstock) has been an eye-catching development platform since its concept was proposed. In essence, RSK is to build a decentralized and Turing complete intelligent contract platform similar to Ethereum. However, RSK is based on the bitcoin ecosystem rather than an independent blockchain. The specific way is to use the side chain technology. This approach has both challenges and great advantages
smart contract platform:
smart contract is the current research hotspot. Nick Szabo came up with the idea 20 years ago. Generally speaking, it is an electronic contract that can be executed automatically based on trigger conditions. Smart contract is the next generation of procts to realize automatic execution in various business environments, which may subvert the existing business model. For example, on-demand economy, such as insurance contract customized according to each journey, reaching the set end of the journey or writing a program to determine, and then the insurance contract ends. This insurance mode can even be connected to P2P mode, which makes traditional insurance companies useless. These simple examples can be realized through RSK smart contract platform
The advantages of RSK:
RSK has many innovations. Firstly, Turing complete virtual machine is compatible with Ethereum virtual machine. Ethereum contracts can be run on RSK virtual machines. The goal of RSK is to achieve 20 seconds block time and 300 transfer transactions (TPS) per second at the first launch, which can be expanded to 1000 TPS. It has reached the level of PayPal, but it has not reached the throughput of credit card network. Compared with other platforms, the biggest advantage of RSK is the combined mining of bitcoin, and the security level is equal to that of bitcoin network. But it also needs to persuade miners to implement. RSK revealed that they will make miners profitable, and the implementation of the contract round fees will make miners profitable. It is likely that the RSK platform will be very popular and the contract execution will reach a stable level
