I always go by the rules of CAPITALISM - cos it works.
You do not need to justify dev fees, competition will do that.

Its simple really, if your hashrate (minus devfee) is not on par or better with other present or future competition - don't expect customers.
Even if it is on par - clients will not switch to setup and lose mining downtime + lose a familiar/accustomed miner + lose a stable setup + lose community/support....

Make the cheese big enough and they will come.


Sgminer is already on a lyra2z prerelease but atm poor hashrates for me, and tdxminer (6+MH/s) hopefully will come out with a windows release - so it will be wise to establish a good user base soon.
