One of the best way to make BTC is to work for fiat then exchange the fiat for BTC Or work directly for btc see services section
service section is mostly signature and selling stuff, not gonna help anymore, you can't call it a real job, it's few pennies a day at this point, if bitcoin skyrocket then maybe...
right now i can't see anyone paying a full wage directly in bitcoin, it would be fabulous but it's not gonna happen in a short distant future
