Bitcoin Forum

Hi, I just published https://topcryptocurrency.exchange (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.

Disclaimer: the site contains some affiliate links, but they do not affect scorings or site functionality. They're a better way than ads to keep the servers running.

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!

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.

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.

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.

Graphs are coming! I just need more data and to hone the algorithm first.

Yeah, Microsoft Flow is similar to Zapier and IFTTT but it was less advanced at least when I looked into it while it was in beta. I remember to see something to analyze the feelings on Twitter. Useful for example if a brand is monitoring its reputation, that's why I thought you were using this

I wanted to say an article for each exchange to introduce it, listing the features etc....

Wow, that proposal would be great and amazing if it will really do a great result. I will be waiting and watching it! Hope this will succeed!

You got a great project...so soon!

Thankful. A useful site, I travel a lot and sometimes I have to withdrawal cryptocurrency in different countries. With this information, I can find out the better to use in different countries.

No matter which country I choose, I can't find some of major cryptocurrency exchanges like Binance, KuCoin, YoBit...
Also your algorithm for reviews is too harsh. This is not realistic that the highest score is about 50-50 positive and negative reviews.

I honestly don't know how representative of anything this data could possibly be. The only thing this would seem to indicate is how people on Twitter are feeling. Twitter is a declining platform, losing users frequently and the users that it is maintaining are increasingly becoming a niche. The people that I have seen promoting coins or getting excited about coins on Twitter are absolutely clueless about cryptocurrency and base their opinion primarily off of whether or not the coin will "pump" before it "dumps".

I've never had a productive cryptocurrency discussion on Twitter. What is happening on Twitter, or any social media platform is extremely irrelevant to cryptocurrency or any rankings that would emerge from that analysis. Unless you're marketing cryptocurrency advertisements to Twitter users, I am unaware how much of a benefit this data can be.

The creation of his site, certainly not the right purpose. Maybe he's going in there to increase traffic and eat advertising. It's not as accurate as the main pages. Please note this information.
