When I joined this group bitcoin price is around $10,000. After a few weeks it steadily increased to $15,000 and now to $18,000+ and speculations of its anticipated increase to $20,000 is all over the internet. I'm really curious who dictates the price increase since Bitcoin is a decentralized currency. Is it really due to the fixed number of Bitcoin to be circulated and a high demand or is it something else. Bitcoin really is beyond logic, Too Fast, Too High and Too Good to be True. I'm in but I can't still get out this feeling of doubt screaming at me saying Get out of there its gonna crash soon. It helps to read a lot of positive articles and threads on Bitcoin. I hope you can share your Idea on this. Thanks.
