So my current process ltc on coinbase -> cakewallet -> exchange to monero -> send to ledger wallet With this setup coinbase sees that I send ltc to some address but do they know that I exchanged it for monero? Cakewallet uses changenow and they save transactions but do they save ip? I haven’t used sideshift but cakewallet recently added it so would that be better? Main question is hypothetically if the IRS reaches out to coinbase all they would see is that I sent the ltc to some random address correct?
