Hello Kevin...i've been doing my best to educate newbs thinking about investing in Bitshares and using the exchange..there are a few videos out that are telling people they must buy BTS to use as collateral if they want to use BitUSD or other stable assets...it's my understanding that you don't need to put up collateral unless you are borrowing or using leverage..i was never asked to put up BTS collateral when i park my funds into BitUSD...isn't it already backed up by allocated BTS and then verified by Witnesses?? thanks for any clarification..im going to clarify these things on these videos so people can get correct information..cheers friend
