Miners and Leetpro clients using NiceHash Miner Legacy as mining software should take note of the new update to achieve better profitability.

Remember that with the release of NiceHash Miner’s version 2 there are now two different versions of the software. The old branch version 1 is NiceHash Miner Legacy which is intended for more advanced users  while NiceHash Miner 2 is for those who are new to crypto mining and who will appreciate the easy-to-use user interface. NiceHash Miner is essentiallly a profit switching mining tool that chooses the most profitable alcorithm based on your mining hashrate and sells your hashrate for that particular algorithm.

NiceHash Miner Legacy is a little bit more complicated to set up for many different miners as it relies on the best performing third miners for some algorithms and includes miners from Claymore, EWBF, Tpruvot and others in order to maximise performance for a particular algorithm. In comparison, NiceHash Miner 2 does not contain third party miner software and uses miners that are developed by NiceHash itself.
