it is why they are a loser.
of course a good coder can use them.
but a smart coder will use them and not promote them.
Just think of all the coin a smart coder earned on zec or monero.
Once they are mainstreamed most of us are only getting crumbs.
with a 4% devfee (say on average) for bitstreams releasing new/better bitstreams on a continuing basis could be more lucrative than just keeping it for themselves. especially once large numbers of new, more capable fpgas hit the wild.
after all, claymore and other devfee based miner devs seem to be doing pretty well.
