Its easy to say bitcoin is trying to eliminate Us dollar, Euro, banks, gold, silver but practically its seems not possible now even bitcoin is continue to dropping this year its not stable as yet. Still bitcoin has long way to go. I believe in bitcoin potential but first all countries should accept btc in their countries without any restrictions that day we can say bitcoin is getting strong and going on the right path. In the end I must say bitcoin will continue to survive as it does in the past 10 years.
