One of the factors that make bitcoin volatile as it's decentralised system. Central banks manipulate the value of their fiat by changing interest rates.
You can't do this in bitcoin so it's value is very close to the market value. Since there is regulatory commission controling bitcoin, no one steps in when prices crash.
It may be a good or a bad thing, but it is the reason why people flock to bitcoin. To keep the banks from messing with their hard earned money.
Yes, I agree, this is also an important factor .... thanks a lot for the replay : )
