Hello, is there any way to mine with both cpu and gpu at the same time ? I saw that i can pick only one at a time, or am i missing something ?

Hello mate, it seems it's possible to mine with both cpu and gpu at the same machine. Check https://www.reddit.com/r/WaltonchainMining/comments/8diso5/cpu_gpu_tutorial/dxnqxm3 for further details.

Yup, you can mine with both. It looks like you need strong hashpower now though. It is very hard on singles cpus and gpus.

Yes, you are right. if I am not wrong network hashrate nearly tripled
