[Steempy v0.0.4] A Steem Price Bot written in Python

Steempy is now displaying the percentage changed whenever the price moves!

As promised, I updated Steempy in version 0.0.4 to be able to display the percentage changed between price changes along with the already implemented, amount changed which is displayed in bitcoin. This was a pretty implementation, that shouldn't have taken as long as it has but, hey. I'm a human, not a highly dedicated price bot like Steempy.

Steempy also got a few bugs squashed

Although, it was nothing major, I changed the way Steempy spits out his information to be a little easier on the eyes, and not so "cluttered." This makes looking at the price movements a breeze. Another, issue that I was having was how Steempy would start off with a really low value as a placeholder, which would, upon starting Steempy report a significant price increase. This was rectified by using a IF statement to check if Steempy's ```coin_price``` was empty, and if it was, it appends the current steem price into it, which always happens upon starting up Steempy. As always, if you ever notice a bug I missed, leave a comment!

New features in the future?

I plan to add some new information/data to Steempy's brain. That data will most likely be steem trading volume but, i'm not entirely sure what I want to have him do with that data. I'm trying to think of another use other than reiterating what i did with the steem price. Any suggestions would be great!
