Good morning. This is Fennec.
The first release version (V1.0) of the crypto news roundup and analysis site I’ve been developing has been completed, so I’d like to report on the release and give you a brief description, usage, schedule, etc.
The link to the website is here.
First of all, I will write about the specifications of the program in a separate article, as it may be a bit too much text. This article is mainly an explanation of what I have done. So, if you are interested in the implementation of the program or the development of this site itself, you may want to read through the article with the specifications to get a feel for it.
The website COTONOCA is a crypto news roundup and analysis site.
COTONOCA automatically brings up the date and title of the news uploaded to each site and summarizes it.
By changing the display settings, users can narrow down their news search to the information they want and view graphs that change depending on the settings. For now, only a pie chart that displays asset volume (number of news articles) and percentage by time period has been implemented.
One feature not found in general summary sites is the ability to search for individual stocks by entering a ticker. It also has the ability to include information on related companies, products, and people in the search.
In addition, you can select a site, search for a category, or view only news related/unrelated to an asset. In other words, you can use it as a summary site or as an analysis tool for specific stocks.
The information that a company sends out is accompanied by some kind of action.
There are times when this is not the case, but it is clear to everyone that a news site that writes articles based on its mood without any progress, for example, and transmits only ups and downs of charts, will be disadvantaged in the long run. Therefore, in most cases, the information sent out by companies will naturally converge on a pattern that is written only after progress has been made in the long run.
This site uses social inevitability and natural selection to help users determine “how much progress has actually been made” by obtaining decentralized information from multiple sites.
Thus, COTONOCA’s specialty is social analysis in long-term investment.
There is a reason why I said in the previous section that “economic news and crypto-related news are the ‘main’ news”, because it is possible to bring in information from other sites as well. For example, it can handle blogs, corporate websites, and so on. This process of bringing in information is called “scraping” in technical terms.
This is going to be a bit long, but some of you may be wondering, “Is it okay to bring articles written by others without permission? So I’m going to add a little more: I try to scrape only information from sites that say it’s okay to bring the information. So I check in advance to see if scraping is prohibited and try not to scrape on prohibited sites.
Some sites even block scraping itself. Scraping is an activity that puts a heavy load on the site’s server, so I pay close attention to the access cycle and the URLs I connect to.
I read the contents of the site, the uploaded “robots.txt” memo, and the HTML source code of the top page to determine if scraping is prohibited.

Asking for Donations
If you find this blog “COTONOCA｜Blockchain Research for Investors” or the crypto news roundup and analysis site “COTONOCA” to be a good service, I would be very happy if you could throw in some money.
The site I created is currently built on the same ConoHa Wing server as the blog. Therefore, there is no cost to operate the site beyond the cost of maintaining the blog.
However, in the interest of ease of use of the site itself, I don’t monetize the site by placing advertisements, etc., so I would really appreciate it if you could support the site by throwing money at it.
Hope you get lots of use out of both the blog and the site!
