What makes BitUSD different is that it is completely reliant on Bitshares assets. This is just one example of the Bitshares ecosystem that Dan Larimer created and how it’s designed, but this type of centralized self-reliance could prove detrimental if one asset crashes, it could bring the whole thing down. (That’s assuming that the whales don’t step in and support the market.)
Anyone can issue their own MPA on the BTS DEX with backing collateral other than BTS - you could back USD with crypto too 👍
