Nice effort. I would like to suggest that maybe in the future, you might want to include a graph indicating how certain parameters are scored against others.
Graphs are coming! I just need more data and to hone the algorithm first.

Cute Idea! However, you need to add more weight based on the number of tweets pertaining to the ICO. Your top rated company has a score of 89% but based only on 9 tweets. I would think that a company with a lower sentiment score but based on thousands of tweets should be more reliable and trustworthy. Also, does your algorithm diffrentiate between unique users?
There's a small boost to bigger exchanges in the ordering, but maybe I need to add a small decrease for some. I like to keep the actual score to be transparent (it's just positive tweets / (positive + negative).)

Only the latest tweet for each user for each exchange is used.

Nice idea. I was ready to suggest to display the tweets (positive or negative) so we get a better idea about the score but it's already in.
I would suggest improving the UI/design, don't take it wrong I know you just started and I am not able to do better btw.
Maybe in future, you can add a page presentation in the menu for each exchange?

Q: are you using something like Microsoft Flow?
Thanks! UI updates are coming, it's currently basically just made for mobile screens. It's a lot faster to create a design that is usable with every screen size and then reiterate for desktop later.

Do you mean like a screenshot of the exchange's homepage with "page presentation"?

This is the first time I've heard about Flow, looks like it's a Zapier copy? It would probably be easy to hook up the Twitter API with those tools, but I like to run everything with Node.js so I feel like I'm more in control.

1. Aside from the algorithm (sentiment analysis) that is being used, are you planning to somehow eliminate tweets that possibly are made by bot accounts (ratings can be abused, if no measurements are in place for such tweets)?
2. Upon clicking the "See more" button, there's no button to get back to the main page (regardless of the back button on browsers).
3. Even though everything seem to be automated, there should be some manual checks as well.
1. Currently, each tweet needs to be unique and by an unique user, so a bot would need to create new accounts and create alternating tweets. I haven't yet seen abuse, but the algorithm could also exclude accounts that are new, have only a few tweets and followers etc. It's always a cat and mouse game.
2. Clicking navigation bar title goes back, but I agree that it was unintuitive. Added a go back link.
3. I do manual checks myself, but there's a lot of data. I'm probably going to create some kind of a report button for visitors to delete bad data (this could also lead to more abuse so not sure yet).

Thanks for the reply!

Hi, I just published https://topcryptocurrency.exchange, a website that ranks exchanges based on a sentiment analysis algorithm that analyzes mood from tweets. It currently has all the data from the beginning of December, and the scoring will get better in the future as more data gets collected.

The system is still very much in development, but now I'd want to get some feedback. There are still more features, exchanges and currencies coming.
