What type of markup for exchanges in json+ld?
Hello.
The site has articles about crypto-exchanges (In them: how to use, rating, comments, etc.)
They are marked as the type "Organization"
Example: Exchange
example Markup example:

​<script type="application/ld+json">{
    "@context": "http://schema.org",
    "@graph": [
        {
            "@type": "Organization",
            "name": "Binance",
            "aggregateRating": {
                "@type": "AggregateRating",
                "ratingValue": "4.35",
                "ratingCount": "180",
                "bestRating": "5",
                "worstRating": "1"
            },
            "review": [
                {
                    "@type": "UserReview",
                    "reviewBody": "Binance - отличная платформа, и я использую ее пол года и не сталкивался с какими-либо проблемами.",
                    "datePublished": "2018-06-26T00:03:36+03:00",
                    "author": {
                        "@type": "Person",
                        "@id": "157",
                        "name": "Аш",
                        "url": "https://example.com/comment/157#comment-157"
                    }
                }
            ]
        }
    ]
}</script>

However, Google support writes:

There are no errors, but you obviously plan to use the markup for other purposes

In this regard, the question is:
And then what type of markup should be used for exchanges?
Or does (type Organization) mean that it is intended to be used only by the organization itself?
Our pages provide information about the organization: (how to use the site (HowTo), review (article), address (if any), user ratings and comments (Review). What types of markup should I choose?
Thank you for your attention.
