Can you tell why you want Cryptopia to be chosen? What are the advantages if Cryptopia will be used as exchanges for PayDay. Really looking forward for your response.
Have some advantages of Cryptopia with others like that :
1. Don't need KYC for withdraw small amount.
2. Quickly confirm for deposit and withdraw via email confirm system.
3. Don't have any strong accusation.
4. Listing a lot of coin, easy for get listing.
On most exchanges, you don't have to verify your account by KYC for small amount, I think on Hitbtc they more chance to get high volume than on Cryptopia.
