Apple changed the requirements for cryptocurrency appsthat you can download in the AppStore. In accordance with the new rules in cryptocurrency applications include: wallets, ICO, cryptocurrency exchange and mining platform. All applications for mining virtual currencies using the chipset of the iPhone have been banned. The software allowed for the extraction tokens on the basis of cloud mining.
The official statement says: "the Application created for the primary supply of coins, cryptocurrency trading futures and other securities, should be developed by financial institutions whose activities are consistent with the law".
The new rules also ban apps offering a reward of cryptocurrency for the execution of tasks.
AppStore policy in respect of digital assets is much tougher than GooglePlay. Four years ago Apple removed all apps related to Bitcoin, but in 2016, was asked to remove apps from the Dash tokens. The tightening of the rules were made as already submitted in the AppStore cryptocurrency applications, and those that are scheduled to run in the future.
