These days bitcoins are not given directly in campaign but tokens are given and very less campaign give bitcoins purely.
What would you do?campaign or trading?
For me, trading and working in signature campaign are both great and this are both giving opportunity to earn money to everyone who want to engage within.
In trading you need capital but through this earning money is easy as long as you have a lot of knowledge and techniques within. Also the important reminders in trading is your patience and don't be greedy.
While in signature campaign, to earn money within is you need to work on it. The one advantage in signature campaign you don't need capital here to earn money. They will pay you on the output from work you rendered.
