Sorry for the noob question but I couldn't find the answer of it so I guess this is the right place
What is the meaning of merged mining actually ? Does it mean we use same resources to mine more than one coin & still get the same number of primary coin + as a gift we get another extra coin ?
OR it simply divides our resources to mine more than one coin ?
e.g. If I have 10kH/s power I could mine about 20 XMR or 120 FCN, so if I use the same hashpower for merge mining, would I get the total of both (20XMR + 120 FCN) or it will be divided to mine both coins & actually I would get about 10 XMR + 60 FCN ?
If your computer mines one coin at 50H/s, if you merge mine you'll get the benefit of both coins being mined at a rate of 50H/s each. No extra power is needed. If you find a block on Coin A, you only get coins for Coin A, but both are hashing at 50H. If you find a block for Coin B, you only get coins for Coin B.
In solo minining (merged mining is a form of solo mining), no matter what your setup is, you only get coins when you find a block, but you get the whole block reward if/when you find a block. If you're pool mining, you get get only what your hash rate can produce, minus pool fees and donations, but you're guaranteed that rate (assuming the pool itself has found blocks. The pool then divides those blocks and pays its miners according to their hash rate).
Solo mining has a factor of luck. Actually, I don't like that word, because "luck" in this sense is dependent upon many factors, some of which are the number of other miners on the network (you're all competing for the same blocks), your hash speed...well, I believe those are the two biggest factors. Someone please correct me otherwise.
