 Hello, if I have several different UTXOs (mixed) in one wallet and I make a transaction, could the receiver see all of my UTXOs in the wallet or just the one they received?

Thank you!  
 They can see all the UTXOs that you spent to fund the transaction. 
 Ok great. So if I were to select 2/10 UTXOs for the transaction, they could only see the 2??

Thanks ! 
 Yes, they can see only the 2.  
 Assuming no address re-use, right? 
 Correct.  
 This mug tho 🔥 
 Though it looks like that coffee never ends if no end tag 
 IYKYK btw I don’t know fwiw✌️🎄 
 I would absolutely love that gift 
 Jameson, what’s your advice in terms of using a passphrase with a Coldcard?

I got mine in the mail today, already setup a wallet but wondering if I should use a BIP-39 passphrase or not. 

Any help is greatly appreciated. 
 I'm not a fan of passphrases because they result in a brittle 2-of-2 setup. If you lose either the seed phrase or the password, you lose access to your funds. 
 What setup do you recommend? I currently own a Coldcard and a Jade 
 Just following up here. Still curious to know what’s your recommended setup for a traveling individual. 

Was thinking Coldcard kept safe and the tapsigner with nunchuck to travel. What’s your recommendation re: passphrase or no passphrase? How would you setup a Coldcard?
