We have added support for T-Rex miner for ZCoin. You can now mine XZC either with our miner, or with an external miner. This means you can either use CCMiner, which you can find in BetterHash or TRex Miner, which you can set up by yourself as an external miner. Both are mining on the MTP algorithm, however they report shares to BetterHash in a different way. We have modified BetterHash so it receives shares correctly from both miners.
To use an external miner, simply access your online account and go to Settings/Pools, in order to get the credentials.
