Well, diff is high, but 95% comes from the same source (can be seen from the LTC payout address in the parent coinbase). Currently, this coin is not secure at all.
I'm working on a merged scrypt pool, it will be LTC/USC initially. Payout PPS. Bonus for finder of block. Pool interface will be like bitparking.
Stay tuned...
In fact 99% comes from us. Yesterday (UTC) we mined 536 blocks out of 543.
We are also introducing UnitedScryptCoin merged mining today. For every Bitcoin you mine at our pool, you get 1 USC, and for every Litecoin you mine, you get 5 USC. BTC/LTC/USC daily auto payout at ~04:00 UTC if balance >= 0.0005 BTC/0.01 LTC at 00:00 UTC on that day. BTC/LTC PPS at 4% fee.
We are currently world's 3rd largest Bitcoin mining pool (after GHash.IO and BTC Guild) and 2nd largest Litecoin mining pool (only after WeMineLTC).
Our website is currently only in Chinese.
