Why would the price of BTC make any difference? The service is supposed to have "No hidden fees" according to your sig. :
It is very shady but a lower BTC price would mean higher maintenance costs in BTC terms so a lower payout would have to be expected.
In order for maintenance costs to not be considered a "hidden fee", they would have to be stated, which they are not. By claiming they have "No hidden fees", they're saying the fees are included in the upfront cost or the fees are well stated. They're neither in this case.
First of all that questions shouldn't go to me. I'm not running this bussines.
These question are not specifically for you, they're for anyone to answer. The quotes are just for context.
AMHASH divs was below 800 (week earlier above 800) satoshi despite lowering maintenance fee.
All is adding up... Even company from your sig behave similiar...
AMHash doesn't claim to have no hidden fees and their maintenance costs are explicitly stated. AMHash's dividend reduced by about 30 Satoshis at most, your dividends from here reduce by a couple of hundred. Given your payout from last week was around 835 Satoshis per Gh per day (which was slightly higher than AMHash's for that period), their maintenance costs would have to be similar to AMHash's. If AMHash only dropped by 30 Satoshis, how do you explain the drop in your payout of 269 Satoshis?
Their behaviour is in no way similar.
