The purpose of the stable coins are to tackle the volatility in the market and give assistance or relief to investors on stability of their investment. That is why stable coins are pegged with another stable assets like US dollar, gold etc. In terms Bitcoin, IMO Bitcoin and most of the altcoins are volatile and are not stable they can go higher or lower in price as per the market conditions, so chances are very very low that we will be able to see stable coins pegged to BTC in future.
