Yes, I have read this article, nowadays more and more stable coins and according to the article above Zhou has no plans to make stable coins supported by the US dollar.
At present, Binance looks fast to develop their projects, there are many new tokens exchanging in the Binance chain and I think this situation will increase BNB prices in the future
Yes it won't be backed up by dollar because it will be British pounds. Binance just never stops of innovating, they have many ideas that gives excitement to the market. First, it was their exchange backed up coin, next the IEOs and then there's DEX. And now, they have this idea of having their own stable coin that will be backed up by another currency and it's first of its kind again. Most of the stable coins has been backed up by US dollar, I won't say this is huge but most of their ideas are unique.
