Bitshares requires some established blockchain to ride on top of, correct?
Even if Bitcoin aproaches a near worthless value, and the trading valume also drops similarely, it will still work to have Bitshares ride on top of it, right?
And also, how hard would it be, if Bitshares started up, and ran on the Bitcoin block chain, for a while, how hard would it be to switch this to some other block chain that was out competing Bitcoin?
