Getting your first bitcoin can be done on all kind of methods one of them is by campaigns and campaigns can be done free so that is also very nice if you ask me.
participating on a campaign is not bad, and it is also one of the most favorite way to earn bitcoin. but getting a whole bitcoin with this method? you may get a whole bitcoin but it will take 6 to 7 month. your current signature paying you 0.035 per week and 0.14 per month, now you can calculate how many months you have to work to get a whole bitcoin. but good thing is it is a free job.
