CoinField is one of the first exchanges I have started exploring as they were XRP centered and that are my favorite exchanges. With XRP the withdrawal fees are never a concern. There are a lot more with CoinField such as fiat gateway and a lot of fiat to crypto trading pairs. They have a close relation with Sologenic so you can get in refferal program free SOLO tokens (was my case). They do not have their own native token but utilize SOLO instead. The Sologenic cooperation brings their special debit cards with lot of upside. The metrics are average such as liquidity, fees and number of users. There are not so many trading pairs in general. There is only staking feature for SOLO tokens. It would be nice to add more. There are no other features such as derivative market etc.
Overall it is a good exchange worth to try, especially if you are Sologenic fan.
