Bitcoin to me has changed history because there has never before been a money supply that is digital and also cannot be printed or manipulated. Governments are helpless at changing the bitcoin system at it's very core and I think that strikes fear into them. I think that block chains are more trust worthy then government and we should continue to innovate using the block chain to make a better world for us all. I cannot wait to see what the future as to hold for us all. We will soon see great events take place. Event's that will shape the very history of are existence, this I am sure of.
