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.?
Nah, I just play (legal, bought) games, run a MWB and BitDefender scan daily. I'm pretty certain the system is clean and secure. That being said I've since learned that ColdCard policy states that they don't make customers send their devices back, so I'll just wait for the new one to arrive and just restore my backup to it. No need to move my BTC anywhere.
