Capturing BTC price with Python

1. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis

above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized

Peter boockvar, chief investment officer of bleakey Consulting Group. I won't be surprised if the price of bitcoin drops to $1000 to $3000 in the next year, because bitcoin is not really relevant in this $19 trillion economy. Any commodity with a parabolic rise in price will usually fall back to the starting point< However, I'm not sure whether bitcoin will slow down or plummet suddenly

the implementation of loose monetary policy by central banks such as the Federal Reserve is the main reason for people's enthusiasm for virtual money. As interest rates graally return to the right track, virtual money will collapse. Once there is a crack in the virtual currency market, investors' attitude towards high-risk assets will also change, and the stock market may be injured. All this depends on the market psychology and has nothing to do with the economic fundamentals. "

Emma, the first one is scared to pee, so hurry to add a BTC

Soros

"as a currency, it should have a stable value storage function. The fluctuation of bitcoin in a day can be as high as 25%, which means that it is not feasible to pay wages with bitcoin

compared with the rapid collapse, the price of bitcoin may remain at a flat high. The reason why the outcome of bitcoin may be different is that some people, such as dictators, want to store wealth overseas through bitcoin

, however, can not change the nature of bitcoin as a typical bubble. It is based on misunderstanding as well as tulip fever. p> It seems that BTC is not reliable. But an alligator is an alligator. There's something in it, but it's not clear. I have an epiphany. You can do it yourself

Robert Shiller, Nobel Laureate in economics and professor of economics at Yale University, reminds me of the tulip craze that took place in the Netherlands in the 1640's. basically, bitcoin has no value unless some market participants believe it is valuable. In contrast, gold has some uses even if it is not used as an investment commodity

up to now, people still pay for tulips, and sometimes the price is even quite high. In contrast, bitcoin is afraid to collapse completely and then be forgotten by the public. However, bitcoin may still exist for a long time, or even last for 100 years "

I don't understand, thank you

"Bitcoin and blockchain attract people's attention because they think it's an 'interesting experiment'". If it succeeds, it may change the world more than the Internet

however, it is also possible to fail, and the probability of failure is at least 20%. It is suggested that the amount of cryptocurrency held should be controlled within the range of bearable loss

the main reason for bitcoin's failure is that people put too much money into bitcoin and can't afford to lose money. "

raise so much money from all over the world just for an interesting experiment? Give me 0.005 BTC

dailyfx, a professional financial media of Fuhui group, said: "as the price of bitcoin failed to rebound to its historical peak in December, the price continued to fall. But objectively speaking, although the price of bitcoin fluctuates greatly, it will not fall by 50%. On the disk, the price has obvious support at the 11750 / 160 level, and the price rebounds above or after touching the support level; If the price falls below this point, it may continue to fall later

the price of Ethereum may break through the current slope area, but it will reach 1380 in the short term from the low point of 500 in December, or it will show that the bull rally is almost exhausted. Therefore, if the price does not fall in the later period, it will be more likely to consolidate. At present, the first support is at 863. If the price is still up, it will be a good opportunity for bulls to make another correction

in the later period, Ruibo currency may be in the trend of high consolidation or downward correction. As the price fell below the support level of 2.1577 yesterday, it continued to fall. In view of the sharp rise in prices last month, it is still unclear which point the current price will stabilize after falling or hitting. Therefore, it is still necessary to be cautious about the trading of Ruibo currency. "

The stock review has been changed to currency review. Brother, I recommend a coin circle of Guizhou Maotai

Dennis gartman, founder of the "king of commodities" gartman news agency, said: "nothing can change my skepticism about bitcoin. Bitcoin will bring disaster to all those involved. At the same time, once this happens, investors will rush to the gold market. There is no doubt that bitcoin will fall below $5000. "

It seems that it is necessary to collect some gold

2. Good prediction

cesares, member of PayPal's board of directors

"the probability of successful bitcoin and blockchain experiments is more than 50%. But instry participants must be patient, because it will take another five to 10 years to achieve solid success

if the experiment is successful, the world will be very different. By then, the value of a bitcoin will reach one million dollars. Therefore, most people in the world will want to buy bitcoin in the price range of $14000 or $20000. "

previously, it was said that the probability of failure is at least 20%. Now it is said that the probability of success is more than 50%. You have all the good words and bad words. Do you owe a BTC

analyst van Petersen of Shengbao bank

"the price of bitcoin is likely to reach $50000 to $100000 in 2018. Digital currencies other than bitcoin will also soar

first of all, you may think that the price of bitcoin has been properly adjusted. After all, it has dropped by 50%, which is healthy. But we haven't seen the full effect of futures contracts

this year, Ethernet may surpass bitcoin, and it will appear later than bitcoin, but it has a more unified leadership position than bitcoin. "

He was right about this guy last time. When the transaction price of bitcoin was below $900 in December 2016, he predicted that bitcoin would reach $2000 in 2017. As a result, bitcoin exceeded $2000 in May 2017. However, it is predicted that eth will surpass BTC. Well, it's not impossible for the second child to seek power to usurp the throne and kill the first child. It's just difficult

Michael Graham, analyst at canaccord genuity, an investment company, said, "one of our themes is that more institutions will enter the cryptocurrency market in 2018. The number of institutional investment procts related to bitcoin is increasing. Regulators will approve a bitcoin Trading Fund in the second half of this year or early 2019

I confirm that this year, the public will see IPOs from some encryption companies and more widely from blockchain companies. "

it's better for me to break the news! CBOE applied for six cryptocurrency ETFs at the end of 2017 and may go online in 2018. What the hell is this? That is to say, it increases the opportunity for institutional investors to have close contact with cryptocurrency and opens channels for professional speculators

Tom Lee, co-founder of fundstrat and super bull of bitcoin, predicts that the bottom of bitcoin will be about $9000. If it falls to this position, we will buy strongly, and $9000 is the best time to enter this year

it is estimated that bitcoin will rise to US $25000 by the end of the year and US $125000 by 2022

bitcoin has experienced many ups and downs, but it always stands back to the previous high point, and the low point becomes a good opportunity to buy

since the middle of 2016, bitcoin has risen more than 75% for five times and plummeted more than 25% for six times. Similar ups and downs in the stock market will take several years, but the virtual currency world can do it in a few months

also optimistic about three kinds of virtual currency. The first is eth, which has the function of smart contract and has a bright future. It is estimated that eth will rise from the current US $1000 to US $1900 at the end of this year. The second is etc, a virtual hybrid of bitcoin and Ethernet, which will rise from the current $25 to $60 at the end of the year. The third is the virtual currency Neo developed by China, whose price will rise from US $114 to US $225 at the end of the year. "

Say! How much did the project give you? I'd like to introce you to Mr. Ali, chief investment officer of blocktower capital, a cryptocurrency investment company; Ari Paul

"at some point in 2018, the price of bitcoin can be as low as $4000 or as high as $30000."

Go away

Julian hope, co-founder and President of tenx

"bitcoin may break the $60000 mark in 2018, but it may also drop to the bottom of $5000, but it's not sure which one will come first, surprise or scare."

go away + 1

Nick colas, analyst of datatrek research, a data analysis organization, said, "the fluctuation of bitcoin in 2018 will exceed that in 2017, and the fluctuation may range from US $6500 to US $22000, all of which are reasonable valuations. And $14035 would be a reasonable median. In addition, there will be four price collapses of bitcoin in 2018, with the magnitude of each collapse being about 40% or more. "

are there still four opportunities for bottom selling and position increase this year

George Tung, co-founder of cryptos r us and a veteran of cryptocurrency investment, will we see another virtual currency whose market value exceeds that of bitcoin? Yes, I believe it is absolutely possible in the next three to five years. Or as soon as three years, there will be competitors who can compete with bitcoin. "

the 3000 year old little demon wants to kill the 7000 year old demon? It's still tender

Lex Sokolin, global head of financial technology strategy, automous research, said, "the currency circle may usher in a new round of" furcation frenzy "in 2018, with a maximum of 50 furcation times!"

Pro, we are here to talk about the price. What do you mean by having a second child

3. Xinwei B3, ant S9, yibit, Shenma, how do you want to mine? brother

4.

In early August, bitcoin 24mining, a cryptocurrency investment boutique, launched a price forecasting model, which uses bitcoin mining machine learning software of bitcoin 24mining in Python. As the upstarts say, burgercrypto revealed in their model that they expect bitcoin to fall to a low of $8000 in October 2019

when the model was released, analysts called on BTC to restore its upward trend to a new historical high of more than $20000. However, as you may already know, bitcoin 24mining's machine learning based bitcoin mining model has proved to be correct. With the increasing bear market pressure, BTC fell to $7700 at the beginning of this month

as shown above, the model shows that bitcoin fell to about $8000 at the beginning of October when it bottomed out, began to rise, entered Halloween / early November, and then soared to an all-time high

5. I have, there are Python entry-level to advanced, python actual combat projects, python + AI all have!!!! But I can't send links

6. Now there are so many partners who are keen on crawler technology, nothing more than because crawler can help us do many things, such as search engine, data collection, advertising filtering, etc. take Python as an example, python crawler can be used for data analysis and play a huge role in data capture
but this does not mean that if you master a python language, you will be familiar with crawler technology. There are many knowledge and specifications to learn, including but not limited to HTML knowledge, basic knowledge of HTTP / HTTPS protocol, regular expression, database knowledge, the use of common packet grabbing tools, the use of crawler framework, etc. And when it comes to large-scale crawler, we need to understand the concept of distributed, message queue, common data structure and algorithm, cache, and even the application of machine learning. Large scale system is supported by many technologies
how to learn crawler technology with zero foundation? For confused beginners, the most important thing in the initial learning stage of crawler technology is to make clear the learning path and find the correct learning method. Only in this way, under the supervision of good learning habits, the later systematic learning will get twice the result with half the effort
to write a crawler in Python, you first need to know python, understand the basic syntax, and know how to use functions, classes, and common data structures, such as list and dict. As an entry-level crawler, you need to understand the basic principles of HTTP protocol. Although the HTTP specification can't be written in a single book, you can read the in-depth content slowly in the future, and the later learning will be more and more relaxed when theory and practice are combined. As for the specific steps of crawler learning, I have listed the following parts for your reference:
basic knowledge of web crawler:
definition of crawler
function of crawler
HTTP protocol
implementation of crawler using
Python mole:
urlib3, requests, lxml BS4 mole general function
get static page data by using requests mole get
get static page data by using requests mole post
get Ajax dynamic page data by using requests mole
simulate login website by using requests mole
use Tesseract to identify captcha
scrapy framework and scrapy redis:
scrapy crawler General description of framework
script spider class
script item and pipeline
script crawler class
realize distributed crawler through script redis
with the help of automatic testing tools and browser to crawl data:
selenium + phantomjs description and simple examples
selenium + phantomjs realize website login
selenium + phantomjs realize dynamic page data Crawling
actual combat of crawler project:
build search engine with distributed crawler and elasticsearch

7. Python language has become more and more popular in the past two years, and there is a reason for its graal rise
such as market demand, easy to learn, support for multiple languages... Of course, these are very official
to put it bluntly,
to write a web service, you can use python
write a server script, you can use Python
write a desktop client, you can use Python
to do machine learning data mining, you can use Python
you can still write test tool automation scripts in Python...
Python language is supported for free
since it's so good, how to use Python to do meaningful business for money
today, Xiaobian will learn Python crawler technology with you< Learning to prepare in advance is a good start, especially in language learning. Interest is the best teacher. When learning crawler technology, you can set a goal for yourself, such as crawling the data information of fashion website for sister paper, packing it to her ·····
basic knowledge must be mastered
what is crawler? Where does the data come from? These basic knowledge points can not be found, please search by yourself! You also need to master:
· HTML, understand the structure and content of web pages, and help subsequent data crawling
· Python
because it is relatively simple, zero basis can listen to some Daniel's blog articles, or listen to what others say
Python plays with automated testing. Students with basic knowledge can skip ha ~
· TCP / IP protocol, HTTP protocol
to understand the basic principles of network request and network transmission, and help them understand the logic of crawlers when writing crawlers in the future< Second, the idea of crawling the whole website
click the web address to see the image, which is the user input the web address - DNS server - server host - server request - server parsing - send browser HTML, JS, CSS - browser parsing - parsing image
the crawler needs to crawl the web page composed of HTML code, and then get the image and text< Third, environment configuration
environment configuration is always the most important environment, which is known to all who have done the test. Python is the same. We need to master several useful ides. Let's take a look at the common ones:
1. Notepad + +, simple, but the prompt function is not strong
2. Pychar is used for the functions of general ides, such as debugging, syntax highlighting, code jumping, etc. it can also be used for Django development, supports Google App Engine, and even cooler, pychar supports ironpython
a good development tool is the premise of all work.

8. Small turtle 0 basic introction learning Python is a free course, there is a video on BiliBili Bili. You can go and have a look.

9. Hello, learning python programming language is the best choice for you to enter the programming world. Python is more suitable for the field of artificial intelligence than other programming languages. Using Python in artificial intelligence has more advantages than other programming languages. You can go to the official website of our college and have a python video tutorial. Whether it's learning any language, basic knowledge, or basic skills, is very important. If you find a teacher or elder martial brother with rich programming experience to lead you, you will avoid many detours, and your progress will be much faster. No matter what our learning purpose is, we have to say that Python is really an excellent programming language worthy of your time to learn. In the selection of training, we must compare teaching, teachers, projects, employment, etc. carefully.
