In a recent App-store guideline update, Apple has decided to put a stop to cryptocurrency mining on its devices. They justify this move by saying that “Apps should not rapidly drain battery, generate excessive heat, or put unnecessary strain on device resources. Apps, including any third party advertisements displayed within them, may not run unrelated background processes, such as cryptocurrency mining”, later adding that “apps may not mine for cryptocurrencies unless the processing is performed off device (e.g. cloud-based mining)”.
Other guidelines regards cryptocurrencies have not been changed and they all seem logical. For example, Wallet app developers must be enrolled as an organization. Exchange apps must be approved, and ICO’s must come from established banks, securities firms, futures commission merchants or other financial institutions and must comply with all applicable law.
All this seems fair to the customer, as cryptocurrencies are still something unknown to a lot of people. These guidelines can exclude the possibilities of scams or apps that secretly mine cryptocurrencies through user devices.
In my humble opinion, this goes hand-in-hand with the Apple policy, since their company promise perfection within their products, and they cannot tolerate the idea of a customer being cheated from third-party apps.
