So I have a binance account that has been verified with legal documents. Would it be fine to transfer bitcoin from coinbase-> verified binance account then trade that bitcoin for XMR then send the XMR-> tails monero wallet->market? Or would the fact that I have verified my account allow LE to trace where the XMR is being sent back to me?
Yes that's fine as Binance, who have you docs, have no way of knowing what's happened to the XMR once it's in your tails wallet
XMR is untraceable in this way unlike BTC where LE would be able to make that link
