Why do something like this? For the fun of it, mostly. Definitely not for this reason:

By creating a crypto trading bot that buys bitcoin every time the Tesla boss tweets about it you can rest assured that you are going to catch a VIP seat on the rocket that will slingshot right past the moon and make its way directly to Mars, where Elon spends most of the summer months due to its cold weather and dry climate.

Lulz aside, I love posts like this because they demonstrate how someone tied together a bunch of disparate things (Twitter API, trading API, regular expressions, etc.) to accomplish a real thing, no matter how silly/foolish that real thing is.

Also check out part 2 where he adds sentiment analysis. (Although, it’s hard for me –a human– to decipher Elon Musk’s tweets, so the results of said analysis are probably no better than flipping a coin.)
