Your site is even still in Russia, not English.
You can switch between English and Russian in the site.
We don’t hold people crypto as we don’t have build in wallets on the website for customer you make order request for cash deal then customer coming to office and swapping crypto to cash or cash to crypto after signing the exchange contract and passing kyc.
You may not have in-built wallets in your site, but you provide deposit address to your customers and they lose custody of their coins when they use your service, so if it turns out to be an untrusted service, they can lose their money. I don't really understand so much about your service, you talk about physical office in Dubai and kyc, i would choose to stick with reputable instant exchanges that do not require kyc, nor can confiscate customers funds and request for it, i.e. eXch.cx.
