maybe get it from faucet?
still a newbie tho. would be great to get to that 0.1 later
nope, really you can't earned 0.1 btc just only with doing faucets, it's just waste your time.
0.1 btc in a month? boy, are we humble! 0.1 btc in a day is easily possible, if you are smart and not stuck in thinking just about what people here are talking about (sig campaigns, gambling, mining, faucets, and all that other bs junk).
yup, easy, just put 1 btc at 90% chance of win, close your eyes, and clicked high/low, if you win, you'll get 0.1 btc easily, isn't it?
