What have you invested and/or thinking about investing in this week?

I would just like to bring up a question to get a discussion going in the comments. Bitcoin has now passed 5300$, which is amazing. And for you holding a lot of bitcoin, congrats. But the question is "what altcoins have you invested in this week, and why?". 

Just post a comment and let's discuss. Share information, i think everyone could learn from it and it's cool to see what everyone thinks about the different coins and their idea behind their investment.
