its not imposible if you are a developer..you can make 1 or 2 bitcoin in a month
but trading too will make you earn btc...
That's true, you can really earn big when you are a developer, opportunities are always waiting. However, we can't deny the fact that you are not the only developer, there are plenty out there, they are competing with each other, and because of that competition, others are forced to just lower their rate so they could get the project.
And also, I think not only the developers can get the bitcoin 1 or 2 in a month, the managers
of the Signature campaign in this forum I think also can getting 1-2 Bitcoin/month. For manage a Signature campaign,
maybe they can get 0.1 BTC. Certainly, plus the results of the Signature campaigns which they are joined.
