People believe bitcoin is backed by nothing. I think that is not the truth. I believe bitcoin is actually backed by people themselves. It is backed by none other than just you. We all witnessed the price has been fluctuating by all those FUDs and bad news. The price changes by emotion and non logical facts. I believe you hold bitcoin no matter what happened and would happen, and believe it is backed by all of us, it would make a history. 
of course bitcoin is supported by many people, if it is not supported maybe bitcoin will not deliver the highest prices like last year. and I'm also sure those who hold bitcoin have confidence that next year bitcoin will reach a high price even more than the previous year. so we only need time to be patient until the time comes, don't be tempted by uncertain news. because that will only cause panic
