Just do some signature campaigns, its easy and also a good thing to do because its easy and also a nice way to make some good money with it.
Of course its depending on what you want to do but I think its one of the best methods to get some nice free non risky bitcoins.
It is easy but that is not for everyone, if you do signature campaign you are like applying for job that the employer will check on your past records as a basis for their decision making. So if you are still a newbie now, do not ever spam as campaign manager hates that.
