TThe SatoWallet Exchange platform is one that happens to be the first of its kind to me. This is because it is the first platform in relation to the blockchain network I've ever seen from the United Arab Emirates (UAE), Dubai to be precised.
The platform happens to have their mobile applications available for both the Android and iOS and they also have their service available via the web, this would make operability easily accessible.
As for the crypto pairs, they seem to have a fair number of crypto pairs. These pairs comes in hundreds and I find it a really good score. They also have their own token, SatoWallet Shares (SATOS). I don't really find much use cases of this token except for the fact that holders gets a 40% dividend share from trading fees. The more the SATOS, the more the returns. The wallet is also known to allow staking of some cryptocurrencies too.
