McAfee 'Coin of the Week' Bot

MBot retrieves the symbol and coinmarketcap.com URL for @officialmcafee's 'Coin of the Week', and automatically buys it on an exchange, currently only Bittrex. It uses OCR to extract the coin information from the image embedded in McAfee's tweet.

WARNING

This tool trades with real money. The author is not responsible for irresponsible usage. Run in a secure environment to prevent exchange keys from being compromised.

Install

git clone https://github.com/shanev/mbot.git
cd mbot && npm install

Setup

Add a .env file with API keys. Bittrex permissions have to be set to trade limit under Settings -> API Keys. Google credentials are needed to do OCR on the tweet using Google's Cloud Vision API. Base64 encode the keyfile into GOOGLE_API_KEY_ENCODED.

Advanced

MBot emits an event with the coin symbol and tickerId when it detects a new coin of the week. tickerId can be used to construct a coinmarketcap.com URL.

Usage:

const coinEmitter = Tweets.coinEmitter;
coinEmitter.on('data', (coin) => {
    console.log(coin.symbol);
    console.log(coin.tickerId); // https://coinmarketcap.com/currencies/[tickerId]
});
