Should I invest in Bitcoin?

I'm not as literate in cryptocurrency as most users here in Steemit, but I've been quite curious regarding Bitcoin recently. I've read some news about Bitcoin having a slight decrease in value and it keeps dropping significantly over the past few days. Somehow, I'm tempted to invest because a significant drop in value like this is somewhat rare(I think). I got even more tempted when I saw Hive account@jrcornel 's post about a person who invested about a million US dollars to Bitcoin.

So, what do you think? Should I invest in Bitcoin this week? If no, then when should I?

Cheers!
