I am planning to move to another state soon, and a colleague suggested keeping a small portion of my emergency savings in digital currency on my phone just in case my main bank account gets temporarily locked during the transition. It sounds like a smart safety net, but I have absolutely zero knowledge about how to acquire or store digital assets. I am really afraid of making a mistake on a complicated platform. Can anyone suggest an exceptionally simple, beginner-friendly tool where I can set this up quickly and safely without any hassle?
