What do you mean by coins? Did you mean Bitcoins?
There are strange things in this topic and a lot of red tags so I recommend everyone to avoid such services.
If you are from the UAE and want to buy or sell Bitcoin, I advise you to use

1. seller/supplier should send coins first and payment after 1st confirmation. online wallet ID will be provided to transfer coins and usually it takes 3 minutes to 30 minutes to confirm depends on network load.
Who will trust you to send you first?
