this thread a question comes up to my mind.
If in the future, you can pay with bitcoin almost everywhere, how are you going to pay? The safest way to store your coins is to use a hardware or paper wallet (properly created). But in order to pay for a coffee at the coffee shop you cant use it, unless you carry your laptop or tablet everywhere.
Using your mobile isnt safe. At least as safe as using hardware or paper wallets. So, how do you think it will be done? Transferring just small amounts to your mobile? Maybe hardware wallets will have a mobile version?
for me this is the same like when we are "using our money" with our mobiles with banks app, for me it works in some way the same so we don't need to be that worried about those changes which are focuse on our phones.
