Friend, where do you see the statistics of the TOP-10? For some reason, none of the found resources, we have not seen Coineal there ... Maybe you can send link?
Coineal was top 12 right now but it was top 10 few days ago.. you can check exchange ranking thru Coinmarketcap, here's the link for your references -
