Merged mining is like a Physics class to me.
I remember most of my Physics classes. The explaination given by the teacher was alway crystal clear. But later I was unable to do the homeworks because somehow I was unable to translate the theory to pratical examples.

Same thing for merged mining. I understand the basics (I think) but I'm confused with the "How to".
I understand that I will mine GRE and another major coin at the same time (correct me if I'm wrong!). If I take BeMining as example, I will mine RBY and GRE at the same time (and maybe 5 other coins??). There is no registration so I use my RBY adress as username. OK but... how will I receive the GRE coins?
Another question, if I want to calculate the profitability of ming GRE, do I take the current difficulty of GRE or the dif. of RBY? Do each coin keep their own difficulty?
Hey, owner of bemining.net here. You are mining all 7 coins at the same time. You set your miner with your Ruby address, start the miner. Then, visit
http://bemining.net/stats and copy/paste your Ruby address (may take ~5 minutes for your stats to show). Once there, you will see a list of all the merge-mined coins for you to enter your address. Follow those instructions. Upon that coin finding a block, you will get a payout after the block matures and the payout cycle runs. More on Merged Mining (

If you have any questions or concerns, come hit me up in #bemining. I'm sigwo or bemining_op there.
Thank you. Being without registration I did not realize that we still have a kind of profile where we can add other adresses.
