Sent ETHW from Ledger to CEX

Before anyone asks why, made quite good amount quick and bought ETH.

My only concern is, am I risking anything now? I did approve the transaction through MM, so I created ETHW network, sent tokens to CEX, swapped and then sent ETH back to Ledger. Now reading about this relay stuff etc gotta kinda scared of attacks that can happen and possibility that I’d lose my crypto (from the Ledger).

Should I be concerned? Transfer everything to a new Ledger maybe?

TIA!
