bitcoin rising to $1000 won't bring down the world system, but hopefully it brings it a bit closer!
Bitcoin won't take down the world system at any price, but I see no reason why it should be worth less than gold.
I agree, Bitcoin will coexist with existing system. And imo, it should be price much higher, because of it's scarcity, and it is much more transferable than gold.
When we hit parity with silver, I told my financial advisor at the bank that it should hit parity with gold too.. He laught. I'll be very satisfied to go to the bank to tell him parity with gold is a reallity. Maybe before 2014..
