my concern with bitshares is that they ... are starting out exactly how the fractional reserve scam did... They keep a "balance" on site and sell you bitshares credits... this is exactly like the fractional reserve scam of holding a balance... and selling you frn's... how are we to know that bitshares has at least as many coins in their balance as they sell in credits? What is to prevent them from just selling shares that have no btc backing? and therefore printing their own money out of nothing?
