It's actually totally unexpected that it's gone up so much this year but whats really surprising is that it's kept it's value too and not corrected like many people over in the economics sub forum are saying it would. I think this has just proven that $50,000 isn't far off and we could be seeing it in a few years.
I think we keep forgetting supply and demand, with this becoming popular we could see insane prices soon.
Right! Bitcoin going to be listed next year is the catalyst for this price. We may see this continuing as people expects that once listed the price of Bitcoin will hit $20,000. To be honest i'm happy that price is rising but i am scared that it is rising too fast. It is possible that a major correction will happen.
