Why do you need to use DEX if you are doing day trading on blockchain with high transaction fee like Ethereum. Besides Thorchain offers trading of real Bitcoin that’s why it’s fee high.

Trading it off-chain will make it just trading with wrapped tokens which is not real Bitcoin. Just purchased wrapped Bitcoin on less transaction fees blockchain such as BSC if you are just trading off chain Bitcoin.

Crypto holders is now conscious about their holdings and they don’t trust anymore any wrapped tokens especially Bitcoin because it’s not a real Bitcoin.
