why just bitcoin
because bitcoin is and bitcoin was 
do u now what I mean
bitcoin to was the way of the world fight back from the world of control of the big powers
trying to control all the world so one man came up with an idea to give the little guy/gal abit of power back in there lives

but 7 years done the line I think that the big powers are fight back
as soon as u know bitcoin  will be controlled and ruled by one person when no one person should
