as often proclaimed, it's not good to have more than 50% of marketshare stashed at mt. gox.
too centralised. mt gox is like the pendant to any central bank for fiat.
more decentralisation!!!
i wonder what the big players will do after the big sellout.
perhaps start investing the coins they bought cheap with their freshly printed cash
in developement of a centralised controlled market.
welcome to gold and silver times!!!
i agree that a little more diversification to other exchanges is healthy for bitcoin, but mtgox having >50% of trading volume has nothing to do with bitcoin security.
