Last week I switched my mining rig (about 11mhz) from xmr to dero but compared to what is calculated, the reward received is much less, even only 1/2 of that of XMR. Is there any problem?
Why would your reward be the same on one chain vs another chain? Your question hardly makes sense.
What is 11 mhz? It’s not the same mining algorithm so it’s not going to be the same hashrate on both chains.
Use a mining calculator with your actual benchmark from the DERO miner if you feel like you’re not getting the right amount of blocks for your hashrate. Also, if you’re using 3rd party miners or a pool, might want to talk to the pool or check with others on their experience with said miner.
