ProHashing is a Scrypt mining pool which mines multiple Scrypt coins based on their profitability, also called a multipool. Prohashing also takes it a step further by merge mining at the same time to further increase profits. It works well with miners that often struggle on multipools such as the KNC titan. It allows payout in virtually ANY Cryptocurrency or multiple cryptocurrencies. Their 4.99% fee is reasonable based on the services they offer and it still has higher profitability than most multipools.
Many of the most profitable Scrypt hardware, such as the KNC Titan have problems with many multipools, prohashing allows these devices to work properly and allows you to generate reports on your profits.
The combination of merge mining and a multipool makes sense to mine here if you wish to maximize profits, although you are not contributing to the security of any one network by much in this case.
There are other multipools, such as Nicehash and Clevermining, but where miners such as the KNC titan are concerned which do not cope with fast work restarts well this is one of the best pools, although if you prefer multipools nicehash and clevermining can make good failovers in this case.
Prohashing shows live charts based on what you earned and your power cost to help you keep track of profits as shown below:
They offer other detailed statistics such as mining efficiency, etc. For anyone who owns a Scrypt miner this is one pool that is recommended, the ability for payout in any cryptocurrency or even USD via coinbase is good.
Note that while this pool is good, you should also have failover pools on your miner. If you wish to support the Litecoin network directly, you are best if you have a large rig mining in a traditional Litecoin pool or solo mining on your own node.
Scrypt does currently have higher profitability margins than sha256 and this pool seems one of the best in that regard, and it has reliable operation.
