I would get like 100-150 for my current phone

What i want is a cold wallet android device,

If i put it online, once i have the new device,

And buy a phone for like 100, while selling for like 150

Like i can probably find one under 100, if it sells lower

, giving me 50 profit ^~^ and a cold device

^~^

Is that correct?

No its not

Like theoretically yes, i make 50 profit, vut it obviously gets eaten by the 200 inital

So like i pay 100-200, instead of defined cut throat 200

And that function changes, depending on how cheap i get my android cold wallet phone device thing for my banking apps^~^
