to start making bitcoin the best way is to join a singinture campain
to grow your bitcoin i recommend trading(must have a high capital for easy earning, you also have to know what you are doing) or holding(long-term way to earn money)
Everybody is suggesting signature campaign. But I find it too difficult to reply in forums in a meaningful way. Because only for a reason other than making bitcoin we can make meaningful constructive posts. Just for money no one can make good posts.
