Winminer - a reward directly in USD, which may be a mistake. The high percentage of fees and the exchange rate on the BTC have their own rate, where they will unduly deduct additional fees. As a result, despite the first appearance, less favorable than Nicehash. It also happens that it takes nonsense after a few hours to draw something that makes no sense with a 1/3 profit.
Nicehash - the best of all bad solutions. Reward in BTC. It's nonsense to use their new program, use Legacy on NVIDIA and AMD, it's uglier but better
