We have noticed that the value of bitcoin is depreciating this few weeks and over 60 billion dollars have been wiped out in the value of cryptocurrency due the slide of bitcoins value. So what are the possible factors that contributed to the downfall of bitcoins value recently, here are some reasons according to this article;

2. Large selling of BTC by MT. Gox
I actually agree to the article that these two are the main culprit on the downfall of bitcoins value. Let us wait and see if bitcoin can overcome such hurdles this coming months.
As I know several companies have already brought in an action against google and they are protesting their financial development rights.For me its true that there are a lot of ponzi schemes and pyramids but people mustn't make decisions without knowledge and researches.They know that there are a big risk in every business,especially here... Anyway, may this case has a future and court's decision may be good for investors and for people who are looking at new projects.
as for MT.Gox its fact that they have sold a huge amount,despite the fact we will see bitcoin rise again its not a catastrophe..
