In one of the topics I read "If bitcoin will reach $10.000, fiat currency has become worthless"
Do you agree with this statement?
When the Dollar loses value, do you notice how all the other fiat currencies in the world also lose value? In fact, the other currencies of the world don't just "lose vale" when the Dollar falls, they lose more value than the dollar lost.
Same thing happens when GBP moves lower.
This is why Saddam, Gaddaffi etc were deposed from power so that central banks could be installed in their countries. The Dollar has been losing value consistently since day one. But, if every other currency loses 'even more' value - what really changes?
When discussing the fiat system, there is alot more to discuss than what meets the eye.
If bitcoin were to reach $10,000 per coin, the fiat system will not be effected - at all. Bitcoin has a mere 12 Billion $ market cap, not even a blip on the radar of world economics at this point. (But, will be in the future.)
The question we all need to be more concerned with is, when will bitcoin ever have the liquidity to support a $10K per coin rate?
