That's a load of crap anyway, currency don't rise and fall magically and Bitcoin isn't 'losing' value it's the paper money that's losing value and being volatile because of how much money printing is going on and flooding the Bitcoin market, I seriously hope that exchanges aren't going to start suggesting price fixing next because this is what it's beginning to sound like.
Exactly. There isn't a real problem with volatility if you don't convert Bitcoin to fiat currencies. If you leave fiat out of the equation, the volatility of Bitcoin in relation to real goods would be much lower. Apart from that people can cope with a lot of volatility without any damage to economic activity. You just have to calculate the new rates which is no problem using computers (it wasn't a problem before the introduction of computers neither).
Volatility is an artificially created argument against the use of honest trade currencies like precious metals and bitcoin brought up by protagonists of the fiat currency scheme.
