After Binance Bridge is gone how to convert real BTC to BEP or ERC tokens (and back)?

Binance say "Use available trustless cross-chain solution".

But the bridges I checked only allow BEP <---> ERC exchange, not real BTC.

The keyword is "trustless". Is there a "trustless" solution that work without KYC and is secure?

Or we need to use centralized exchange and hope that they will no lock our accounts and demand KYC?

The original announcement:
