Nicehash, where do you suggest to get the most recent and accurate information on what we should use as our password. Do you recommend using your main page for SHA-256? Currently it indicates 0.0119 and wondered if using that number or going up a bit higher to make it worth it? I wouldn't want my rigs switching too many times I guess. May as well want to make it worth it. I also some times do not have the access to change my password field, limited access to my miners. So that in itself could be a bust for me to use this type of proxy hashing. What do you think?
We have "percentage p=" on todo list, where you would be able to only specify % above or below current profitability of ideal 100% luck bitcoin mining. But even this would not solve the possible price tag, where your miners may constantly switch on/off. It is impossible to say what price to set that your miners would never fall into this mode.
It is good practice to use PPS backup pool for switching.
Another option is; you may simply ignore p=. NiceHash paid 4% above ideal 100% luck bitcoin mining in past 30 days and with 2% fee this means 2% above ideal 100% luck bitcoin mining. There are no other pools that can guarantee you this with extremely regular payments. Not to mention extreme spikes that can happen (paycoin for example). Down spikes are not often or very big - we have a lot of buyers that do arbitrage and they pull the price up towards 100% luck bitcoin mining.
If you want guaranteed payment, mine with NiceHash. If you want to gamble, choose other pools or even solo pools.
