100T + seems to be the magic numbers lately.
Funny you say that. I had noticed that not a single person who
rented 1+ PH has ever found a block here. Not sure exactly what that means but as well as some very lucky people there have been some very unlucky people. There is really, however, no way to confirm the hardware you are hiring isn't configured in such a way as to never find you a block mind you so you're always taking a risk (they'd need to be very nasty operators and I seriously doubt they'd risk their reputation with so much hashrate at their disposal but you never know).
Well, just to make a small comment here - hashing power from NiceHash/WestHash is as good as from any physical miner... Maybe even better, because we're the only service that is actually doing full share validation at our side to exclude any possible fakers (
https://www.nicehash.com/index.jsp?p=faq#faqg3).
Also, what you're describing is possible to do on any other pool with physical miners, it's one of the issues of stratum mining where you can't actually know if miners are submitting all of their shares.
Here is a sneak-peak from one of our upcoming features - hashing power buyers will be able to see detailed graph statistics for their order (speed, rejects and other possible target pool issues) and thus will be able to compare purchased hashing power to the one that target pool is getting.
Take a look at the current solo-club 1PH order (times UTC-2):
As you can see the hashing power is stable and "good quality". But I'd like to raise here another issue with "pausing" orders. As you can see, solo-club's order is on pause in particular periods or doesn't reach full speed (due to order's price limitation - this is typical for many big orders). Now, if we're talking about luck (and to be honest, luck is all about solo mining),
what if your lucky moments are exactly in those "paused" periods and you're just missing them? ... just joking
