What advice can you give to someone who wants to earn bitcoins online ,however not through faucets
As @Jak said at first, you can invest, trade or offer your skills to people in service thread.
I think the best idea would be to start signature campaining, gather some btcs, like 0.3-0.5 and then going into leverage trading ( margin trading )
for example on magnr.com or poloniex, obviously before you need to educate yourself.
Then, with some luck your profit monthly can grow up to really big!
