Recently, I've been trading bitcoins on btc-e, earning only a little, yes, very little, except the fees that btc-e takes.
Besides trading, are there any good method to earn bitcoins? Thanks.
If you are asking only of earning bitcoin, we have bitcoin faucets, or altcoin faucets that can be convert into bitcoin.
Then the person can also participate in joining the signature campaign in the ico project.
You can use the cloud miners (many people do not like it, I particularly like it and have already won some bitcoin fractions). Recently browsing the internet, I have noticed some websites that promise earnings (x%) from investments (I have never used them, I do not know if they are legitimate or farce).
