So far bitcoin doesn't have any bridge rather op can move them exchange like centralized exchange to convert to any coin he wants order than bitcoin, you know just as you said it might not be safe for bitcoin to go have a bridge crossing from bitcoin blockchain to another chain, normal I don't think is possible except only for altcoin. We can bridge from Ethereum to Binance smart chain or bridge from Binance Smart chain to Matic with either little or more fees, this is the reason why I don't usually like bridge because you won't get exact value anymore. But the best is to move bitcoin to centralized exchange and convert or trade to any coin she or he wants.
