**Here is an example of calculating the rating for the site CCN (https://www.ccn.com) on August 1, 2018:**

- Calculate points for the number of news:

x – Points for the amount of news,

y – The amount of news per day on the resource,

z – The maximum amount of news per day from the presented resources,

- Calculate points for popularity:

a – points for popularity,

b – Resource popularity per month,

c – Maximum popularity among all represented resources.

- Then we calculate the final score for this resource taking the placed weights into account:

where t - the total number of points given to the resource.

Thus, the site CCN gained 0.55 points according to our methodology, as this is the second largest result of all news resources presented on our site, then CNN takes the second place after Cryptovest.

This approach allows our visitors to choose the most informative resources, which, in addition, monthly are visited by significant number of people.

Since it is quite difficult to find meaningful criteria for ranking of these resources, we rely on popularity among users as a priority in their arrangement. Ranking is carried out according to popularity: the resource with the greatest popularity goes first in the list, behind it-the rest in decreasing order.

We try to identify all people who have weight in Cryptoworld and have made a significant contribution to the development of Cryptoindustry. People in the " People " section are ranked according to the rating of the guidebook. **3 factors are taken into account when counting the rating:**

- The number of subscribers to Twitter account;
- Current capitalization of projects in which the person took part;
- Rating "Top people in blockchain ", calculated Cointelegraph.com.

For each of the factors the person is given points. The highest number of points takes the first place in the ranking.

**Let's calculate the rating on the example of Joseph Lubin, one of the co-founders of Ethereum –on July 19, 2018:**

- Calculate points for the number of followers on Twitter:

where x - the number of points;

y – number of followers of Joseph Lubin;

z – the maximum number of subscribers among all people in the list.

- Calculate the points for capitalization of projects. As the only project of Mr. Lubin, the capitalization of which we can count, is Ethereum, we will take the information exclusively on it:

where a - the number of points;

b – Capitalization of the project;

c – maximum capitalization from the projects of all people in the list.

- Calculate points for a place in the rating «Top people in blockchain» from Cointelegraph.com:

where m - the number of points;

l - rating of the person in «Top people in blockchain ";

n - Maximum rating «Top people in blockchain ".

Now we calculate the total number of points for all three indicators:

Thus, Joseph Lubin gains 1.53 points according to our methodology and takes the second place after Vitalik Buterin, who scores a maximum of 3 points.

The forums are ranked according to popularity: the resource with the greatest popularity goes first in the list, behind it-the rest in decreasing order.

The main criteria for the ranking of companies providing services for the ICO launch is the number of projects launched by them: the company, has the largest number of projects, is the first in the list, behind it-the rest in decreasing order.
