Let's say I'm an Ethereum whale with x million assets in Ethereum.

Is there a way to convert my Ethereum or USDT / USDC to Bitcoin without KYC?

Bisq or HodlHodl are attractive, but the liquidity there is too low for me.

To be honest, central swaps like SimpleSwaps are too risky for me, the past has shown where this can lead.

My idea would be to use wallets like Exodus / Incognito / Ledger / Trezor and convert the Ethereum into Bitcoin in smaller 10 - 20k steps.
Then whirlpool everything and put it on my cold wallet.

Do you maybe have better suggestions for me?
