But isn't every ether transactions shows up on ether scan and can be traced, no matter how many take place. Even if swapped for other tokens/NFTs those leave trace too???
True, but you gotta think multichain multi-dimensional
Let's say hacker trades on Uniswap $1M worth of ETh to USDT, that will be on Etherscan
Then bridge the USDT to BSC, and use pancakeswap convert to BNB that will be on BSCscan
Then bridge to Fantom network and use spookyswap convert to MIM that will be on FTMscan
Then bridge to Avalanche and do the same thing that will be on AVAscan
Then bridge to Terra network
during all those bridging, hacker transfers to multiple addresses on each of the blockchain, kinda like cockroach algorithm explosion to make it difficult to track
Actually the one of the best one is to use Wormhole bridge to Solana as that is not EVM compatible and so addresses on side of the bridge is different on the other side
There's probably other options for non-EVM bridging source-destination

Check out the Tornado cash for lazy way to privacy
It's not a bad idea to have 1 or 5 or 10 eth on Tornado cash that you can just store on that smart contract that you can withdraw in an emergency if you needed to get away in a hurry, NFA
