When I switches phones and easily transferred my wallet to my new device, I realized the loopring app still works and updates actions on the old phone when connected to WiFi obviously. Is this a good back up plan to in case current device gets nuked in some way? Satchel.loopring.eth
Dont answer DMs… or even post your wallet.
But yes, both phones have the key encrypted in your phone. I have a similar situation and I put the old phone in my safe and turned it off
Similarly… if someone finds that phone and accesses it, it could be a risk. So up to you
