I can't see a need for BitBTC in this scenario. Unless I'm missing something, the whole point of a BTC sidechain is that it effectively allows real BTC to be traded on the DEX. Of course, mechanically, that means trading a BTC asset (e.g. SIDE.BTC) that is backed 1-1 by real BTC held in a multi-sig BTC wallet or some other sidechain construct. But the point is, I think this makes BitBTC unnecessary. In fact, theoretically this could be duplicated for any blockchain-based asset such that the need for all the complications associated with market pegging will ONLY be required for "real world" assets such as fiat currencies (e.g. USD, CNY, EUR), commodities (e.g. Gold, Silver, Oil), stocks (e.g. AAPL, MSFT), etc. Where am I going wrong here?
