this is not a mining software itself, only a firmware mod ,
it does not deserve the developer's fee, and this is also a hidden charge, no one can be sure from it.
also the development process is still ongoing and it does not provide additional revenue.
If the algorithm was added, the developer fee was completely worth it.
seems as , it uses the units for experimantal and take share from the profit from them hiddenly
the common thing , mining software takes shares the profit. No one give lifetime profit share to modding.
do not confuse the minds please.
Its not hidden you can see it in the kernal log, its also on the top level post. If you don't think the dev is worth it for 'just a mod' of the firmware, then don't pay it just use bitmain stock firmware, no is forcing you to use it. Honestly if he could actually add additional algo's to the miner he could charge a lot more then 1.5% dev fee.
