I have try nicehash and they give profits per week but it would take time to earn from it so much better to think it first better investing, also nicehash have their own support team here so it will be easy for you to ask help. good luck to you mate.
You will lose money unless mining altcoins and they go up. If your paying to mine on a rental site, you pay higher then normal amount to mine it. So I see nicehash as a hard sell unless you do altcoins, and at proper time.
I suggest looking at the asic gear out there. I assume OP want's to mine BTC. If so look at your electricity cost this will be key in if you profit or lose money. But I would start slow and see how it goes assuming cheap electricity.
I agree, and while I do not like nice/westhash I do still rent when the price is right. Either way renting hash is a gamble and owning your own gear is much better long term when you factor in being able to sell it before it is a paper weight. You also have to factor in power supply costs and possible more depending on the miner.
