It's really simple to take any crypto currency holdings you have and split them into multiple accounts. One of your accounts, that you enable on your mobile device, could have a small amount of currency and even if there were a JavaScript exploit that hijacked your private key, you've only lost that bit in the small account. And, you don't have to wait for the bank transfer to occur, or even create an account with a bank bureaucracy. It seems much better than the alternative, no?
