Hello everybody!

my name is Alex and I have to make a important presentation for school. I was very interested in BTC and I gained a lot of information, but I am still looking for some very important facts. In two days I will have a test about my presentation and I still need this one info!

WHY has Bitcoin risen to fast at the end of 2013 and WHY is there again this rapid trend?

I know, it's a matter of supply and demand BUT I am looking for reasons like important incidents that show a trend (like the closing of Silk Road or the announcement of Ebay/Paypal that they are interested in BTC). It would be very helpful if you could give me some "incident" facts which had an influence on the market! I didn't find a lot information in german (sorry for this swollen grammar,  my english could be better^^).

I bet this is some kind of unnecessary question for you but for me this is very urgent and I would be very happy if you answer me.

Greetings from Austria,

Alex
