Apple has moved to put a stop to any crypto-mining apps that might be used on its mobile products.
In a recent update, the personal computing company expanded its initial guidelines on cryptocurrencies. Before, the guidelines specified apps facilitating cryptocurrency exchange and/or initial coin offerings (ICOs) must comply with all applicable state and federal laws.
Now, the guidelines specify more than that. In five bullet points, the guidelines run through Apple's policy on wallets, mining, exchanges, ICOs, and rewards that take the form of cryptocurrency.
