My mist-wallet is used for purely for dapp development. To fuel my future ambitions, I went to an online exchange and bought some ether coins and used a mobile-only wallet for these real ether. When trying to research how a mobile wallet differs from Mist-wallet, it seems mobile wallet is a contract and my mobile wallet company participates on my behalf in EVM. If this is the case, how can I trust my mobile wallet company? Can my mobile wallet company transfer all the currency I got into their own and blame it on hackers? TIA
