If anyone out there is curious about this process (which I recently just went through) to sell Bitcoin on your cell phone from a cold storage paper wallet (like found on bitaddress.org) -than this thread is for you. I’ll lay it out step by step -
1) You need to check and see if you have any forked coins (shitcoins) here:

-Download Mycelium app
3) Once downloaded open app and click on “Coldstorage”
-scan private key QR code
-Make sure you click “SWEEP ALL FUNDS”- THIS IS VITAL !!!
-type in the wallet’s public address in which you wish to transfer bitcoin in order to sell
-Confirm it hits your new address and you’re ready to sell
4) Void paper wallet cold storage -No reason to use again & remember Satoshi said to never use a private key twice!
