wow, all these ideas for buying and selling BTC for a profit more efficiently! how about, don't? how about using BTC as a currency, to buy and sell stuff and services like its supposed to be used instead of trying to make a quick buck exchanging it? these kinds of posts are simply proposing to fix the problem by making the problem more efficient 

lets improve liquidity by introducing better markets?! its the lack of liquidity that prevented BTC from hitting rock bottom and the little liquidity there is comes from people trading with BTC instead of trading in it. as with the mainstream economies, its that competitive greed that is ruining the currency, making it more volatile and therefore less suited to exchange of goods and services, further eroding the liquidity - it is supposed to be a cooperative currency and trying to make money from money (at the expense of others) is not a very cooperative occupation 

how about mining pools controlling the sale of BTC (they are after all, creating the currency) or some sort of mechanism to make BTC "rust" (it could simply rust back into mining rewards instead of disappearing, preventing this competitive mindset and encouraging more circulation
