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?
Eventually, if bitcoin is going to get massive adoption, we have to use our mobile to transact because you don't expect people to have to go every where with their computer or with their hardware wallets just because they want to pay for burger or coffee. Yes the phones are not secure but in the spirit of that, a lot of us still have our mobile wallets on our phones even bank apps are all on our phones to make transaction faster. The security concern for me would be in two folds
1. The software vulnerability which the mobile software developers are trying to curb with trust worthy developers, Google overseeing, regular anti-virus updates etc, I think that area would be covered to a large extent.
2. The other security is the physical one where in the case of burglary, armed robbery and being forced to transfer from mobile wallets at gun point or in the face of aggravated assault. This is a great concern that might inhibit that but with adequate security with government living up to its responsibility and personal security consciousness, I think that area is also pretty covered.
