and to answer my own question: yes, it will go up exponentially
Sorry - I must have got confused - but glad that you worked out the answer - are you suggesting that Bitcoin should be changed to allow for quicker mining of blocks?
no not at all. i was just wondering what would happen to the difficulty if some crazy dude with tons of ASICs was to mess with us, and put all the blocks 2 min apart.
i don't about all the 51% attacks, panic and other stuff. i was just interested in the difficulty.
