would it be possible to set a minimum profit level...ie. so no mining takes place until level is exceeded?
Possible is but has sense?, at this moment always is profitable mine i think
if you weighed up the electricty costs...at times i just break even
With what cards and electricity cost?, for example with Nvidia pascal and 0.12€/kw is far away from being not profitable.
ha ha ... i wish my electricity was .12 its closer to .20, and my power consumption for a 1080ti,a 1080 and i7 is 653w
anyway it was just a thought, like i say at times it has come close to just breaking even
