The link shows paying in btc because they don’t give you what you mine. You rent your hash rate and people bid on it with btc. You’re not mining btc directly. I use NiceHash at the moment. Your gpu mines ethereum (or whatever the most profitable coin is as NiceHash has a profit switcher.)
Could you explain to me why someone would offer their hashing power on NiceHash vs. just directly working for a pool? The main cases I image are: 1. The miner doesn't want to deal with price fluctuations and wants to prevent arbitrage risk 2. It might be more profitable to outsource smallish coins that have to buy hashing power to stabilize their network (though that would probably also be covered by the profit switc…
Setting up a miner yourself doesn't take much work but it won't have profit switching or extra cloud features that Nicehash or Minerstat have.
