I understand you can buy coins using fiat. What is your other means to generate coins?
Update:
To avoid confusions; I am asking how do you personally get coins. I understand how the coinbase/mining is carried out.
Depending on your expectations, you might have come at the right time. I see a lot of Airdrops popping up. Participating in them, getting coins for free, then dropping them like hot potatoes as soon as some minor exchange lists them.
There's not much money to be made there, but to get the ball rolling; why not.
And yes, signature campaigns obviously.
