Bitcoin is not going to die easily. This is just a normal fall. I don't find anything to worry about. Yes it's a huge loss to some people but it doesn't mean that this is the end of it. Wait till the next year and I hope you will see the raise again. It's acting like a stock market now. It never dies. Many people are so much panicked since yesterday but I don't find any reason for panic. Holding it till next year would be more profitable I think.
