Just want to add my 10 cents here without the wider Nicehash lovers trying to crucify me.

Now to the point, Nicehash is great but dont just put some numbers in the calculator and get excited. There is a lot more to it and the returns are significantly lower. This is for me and I am working with them to sort/optimize this. Rule of thumb whatever your hash power is reduce this by 10% to manage your return expectations. They seem to have 5-8% high reject rate for me as compared to other pools. Again like I said we are working on optimizing this, its not an accusation just my personal experience. Then please dont add numbers here and get super excited https://new.nicehash.com/profitability-calculator this is a mere depiction for past 30 days and generally IMO 8-14% off.

Infact to get a more accurate picture have a look here https://new.nicehash.com/algorithm and reduce by 1-3%, this is much more inline with what you can expect moving forward. I have my own formula which I use to plan my expected payments for the next 30 days and has been +-5% inline with actual payouts and works for me. Please note it may not for you, use it on your own risk.

Basically reduce the payout by 0.032% every day. I am currently working on an a macro so it go into more detail by directly factoring in difficulty increase and historical (payout, demand and availability) correlation.  Happy to share when ready so everyone can use for their own benefit and comment on it.

Anyways hope this helps you, happy mining!
