Litecoinpool
Introducing the first genuine pay-per-share (PPS) Litecoin mining pool, where each valid share you contribute is immediately added to your account at the prevailing PPS rate. This rate, measured in litecoins, incorporates earnings from merged-mined cryptocurrencies like Dogecoin, leading to greater payouts compared to standard Litecoin pools. Thanks to the benefits of merged mining, there are no fees to worry about; in fact, your total earnings will surpass those from a zero-fee PPS model. This pool is not a PPLNS, SMPPS, or RBPPS setup: we guarantee payment for your contributions, irrespective of whether the pool has resolved enough blocks to meet the earnings generated. Unlike other systems where miners receive rewards only when a block matures—often risking the chance of blocks being orphaned and yielding no reward—our PPS pool assumes the risk of bad luck so you can enjoy consistent earnings without the hassle of variance or orphaned blocks. With our unique approach, you can mine with confidence, knowing your work will be compensated fairly and reliably.
