It is all transparent - you can check stats of your mining progress on
https://solo.nicehash.com (your username is same as your bitcoin deposit address on NiceHash). So, hashes are 100% real, there is real mining going on behind.
I know it is real and I have no doubt about this since your hashes comes from different people all over the places
Fixed orders guarantee you the speed you limit your order to. These orders are top priority order and we always only offer 50% of all hashing power available for fixed orders. That is why sometimes, some high speed tickets will not be available to purchase.
Are you saying that this bitcoin lottery uses the fixed order system for the hashes?
Anyway, yes, your speed may fluctuate up and down, but on longer period of time, your speed is about the wanted one. Moreover, if your speed is lower, then you mine for longer, if your speed is higher, then you mine for shorter period of time. What is important: your chances stay the same regardless of speed fluctuations.
In regards, where does this chances calculations comes from? because as far as I know , there isnt any specific chance calculation yet about solomine ( I could be wrong ) since there is alot of factor to consider such as the downtime
A 1000 TH/s ticket will 100% reach this speed regardless of other buyers. But it may not always be available as explained before.
Since there is a total of 5000 TH/s in nicehash alone currently , does you mean that there wont be another renter if someone decided to rent all 5000 TH/s for the lottery since you will prioritize them?
