Project is no longer maintained. The source coude remains valid but the bot has been discontinued.
This little script is coded in NodeJS and is turning on Heroku.
To run the script : node bot.js
NodeJS bot files : bot.js, config.js, package.json
I have made the same thing but in Python, just for fun.
You can run the script with python bot.py
Python bot files : bot.py, twitter_acces.py
API used to make it: CryptoCurrency Market Capitalizations & Twitter REST APIs
