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.
The dex is trading real Bitcoin on the lightning network, not wrapped bitcoin. Vast difference in security level. Basically if you believe lightning network is the future for bitcoin (i personally do) then the hydranet dex being the only one who has developed a dex solution using lightning is just going to explode in value in the coming weeks. Core dex is already live and web dex is on the way.
