I would say about 0.1btc from just giveaways.
There are some really generous people on this forum.
But you need to be here almost all the time to catch them before they have given out all their bitcoins and then it is over.
yeah. generous peoples are all over the world. but don't defend on only the give aways. the forum is full of a lot of earning opportunity and source. be creative and find other ways to earn bitcoins.
As of now, not much. I am just starting but I think you will earn more in posting your thought here in forum. If you will just keep all your earnings you can then invest it on some sites. Any small amount can turn into big one if you will keep them and not spend on nonsense things like trying to double it by gambling.
Would agree with you. every single bit worth here. specially in bitcoin. if bitcoin price is 590$$ today then it can become 2000$ one day. (not sure but very possible) and that day you'll know how much a single penny worth to store and keep them save. you hard earned money don't that much worthless that you lose them in gambling and ponzi.
BTW I've earned 0.19 once from a monthly signature campaign and it was my highest single earning.
