Cryptocurrency trading - will be rejected?

Read the guidelines:

3.1.5 (b) Cryptocurrencies:

• ℹ Wallets: Apps may facilitate virtual currency storage, provided they are offered by developers enrolled as an organization.
• (ii) Mining: Apps may not mine for cryptocurrencies unless the processing is performed off device (e.g. cloud-based mining).
• (iii) Exchanges: Apps may facilitate transactions or transmissions of cryptocurrency on an approved exchange, provided they are offered by the exchange itself.
• (iv) Initial Coin Offerings: Apps facilitating Initial Coin Offerings (“ICOs”), cryptocurrency futures trading, and other crypto-securities or quasi-securities trading must come from established banks, securities firms, futures commission merchants (“FCM”), or other approved financial institutions and must comply with all applicable law.
• (v) Cryptocurrency apps may not offer currency for completing tasks, such as downloading other apps, encouraging other users to download, posting to social networks, etc.

Generally, you need to be an established trading organization to be allowed.

Thanks for the response.
We read the guideline but it is not clear if we can release an app with such functionality and the Apple support refuses to help in this case - unfortunately. This is why I placed the question here. The concern is if being an "established trading organization" enough.

App Review isn't here. No one here can promise what will/won't be rejected/approved. There are no pre-reviews, All you can expect here are the opinions of, and/or anecdotal replies from, other devs.
