So eventually bitcoin is gonna have to compete with credit cards and mobile payments. To do this people will need to have a bitcoin mobile app.
I know there are the lightweight wallet mobile apps. Are those any safe? Will those be the future. Or will the future be having a hosted service where the company has control over your bitcoin and you can just send them to pay with stuff with the mobile app? Like Square recent integration of Bitcoin.
I don't know what options are out there now. But it would seem to me that having a secure offline savings account coupled with a hosted mobile bitcoin service (checking account) for payments would make sense. I mean I guess obviously if you're making payments you can't have everything in cold storage so some compromises on security must be made.
It is safe as using trezor or any other wallet, the only difference is that you can brig your wallet every where yet the security of your wallet is the same. Just make sure that you have a back up records for you wallet, like the password and the email you are using to access the wallet.
