* Note: the actual mining speed is a bit higher as some of the hashrate is used as devfee. The above values are what you (the miner) gets.
Other miners with devfee show you the total hashrate and then you have to reduce it by devfee: for example,
if you have 30MHs with 5% devfee, then effectively it is 28.5MHs for you (30 * (1.0 - 0.05)).
This miner shows you exactly the MHs that you earn, so devfee value is irrelevant.
You do not have to use this miner. For a free open-source option, please use

so... what is the actual dev fee, for the sake of transparency.
I have no problem with using the software with a dev fee, as long as i know what the dev fee is.
TeamRedMiner has no problems with stating what their dev fee is.
a fee i can write off on taxes when the tax man comes along.
