Don't send your coins to a shitty centralized exchange that might find faults with them and say they are "dirty" and that they need to keep them for everyone's sake. Or you could get them back if you do everything they tell you to and send all kinds of documents. If you must move the BTC from your Coldcard, keep them on Sparrow.

Are you confident enough that your computer is safe and malware-free? Do you use if for any purposes where it might catch malware, keyloggers, etc.?
