Or look over here, they're sorted on the $$$ volume/24h,
https://coinmarketcap.com/exchanges/volume/24-hour/Guys, where I can see the list of all exchangers ?
I use the portal
https://www.bestchange.com/, but as I understood 95% of the exchanges are Russian and Ukrainian.
Is there an analogue of this site, but with the international exchanges?
What do you mean by "not for trading"? What else are you going to use it for? This is literally the definition of an exchange..
