PesetaCoin, HunterCoin and OrgCoin came later, if you are a programmer you can check their code and see the similarities with the USC. Until now merged minind wasn't good because it was only possible with solo mining using P2Pool, but then this pool was developed. I can show you the thread with all the comments, but it is not in English. If you still don't trust me I can show you the first virtual machinewe used for merged mining.
Yeseterday we finished translating the pool into English, and don't understand why it haven't been a lot more successful, because there is not a bad point in all of this, it is just reusing shares. You just have to come and see
Oh, I see what you mean now. I apologize for my earlier remark, I wasn't really familiar with USC and these other altcoins.
I just focused in on DOGE and LTC and I assumed you meant that you had a way to mine them concurrently.
No, you mine only one of the mains (LTC, DOGE, DGC, POT or CAT), and then the others come for free. But if you have for example the 5% of the shares of the pool you will receive 5% of every coin. Obviously you can't merge mine LTC and DOGE, because the code isn't there but, lets say you have a 1250 Khash/s mining rig, it would be like this:
LTC: You would receive it as if you were mining at 250Khash/s (1250 / 5), even if you are only mining other of the mains.
POT: You would receive it as if you were mining at 250Khash/s (1250 / 5), even if you are only mining other of the mains.
DGC: You would receive it as if you were mining at 250Khash/s (1250 / 5), even if you are only mining other of the mains.
CAT: You would receive it as if you were mining at 250Khash/s (1250 / 5), even if you are only mining other of the mains.
DOGE: You would receive it as if you were mining at 250Khash/s (1250 / 5), even if you are only mining other of the mains.
PTC: Full speed, 1250 Khash/s.
ORG: Full speed, 1250 Khash/s.
HTC: Full speed, 1250 Khash/s.
USC: Full speed, 1250 Khash/s.
Obviously we will be adding more merged mined coins if they appear. If a big one like DOGE added that code it would be great, but it isn't possible yet.
Anyway, you are mining 4 coins for free, I think at least it deserves a try, doesn't it?
