Soon or later it will its good that you do it on this way because the fact is that earning bitcoins on this way is safe and without any risks.
I think most likely the bitcoin will rise to a higher amount so its good to earn them free, 100% profit.
I think buying is the best and also the quickest way without risks, also a signature campaign is of course possible it its without risks and pretty easy the only downside is that it will take a long time to gain a whole bitcoin.
