これか。こんなもん、真に受けて掘ってたら、普通に掘るって事じゃん。
優位性なんてどこにもないじゃん。マイナーやるなら、他のマイナーより有利に立つ必要があるわけだろ？

NiceHash adjusts Da (difficulty) dynamically according to your miner's speed:

If your miner is faster and is submitting shares more frequently than expected, NiceHash increases the difficulty.
If your miner is slower and is submitting shares rarely, then Nicehash decreases difficulty.
