Still not recommended like you said, cloud backup have messed many people up, I will only do this if the amount of the total asset isn't that much, in the hundreds of dollars, the moment it's over a thousand in dollars it is best to buy a hardware wallet, how you want to move it around is your problem.

Honestly this isn't the advice we should be sharing base on what OP shared, instead of saying that brainwallet or cloud backup isn't generally bad in this type of situation why can't we advice people to stay away from crime, any type of crime that can get you deported from a foreign country abstain from it.

OP labeled her, the old woman as ordinary, I refuse to believe it, it is nothing out of the ordinary that some people are doing everything they can to survive in today's world, these people can't be clean and still get deported, ordinary residents? They are not ordinary.
