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?
You can do that both, you can choose the campaign if you have no capital to be use in trading or investing. After that you can use the earn salary iin trading for extra profit. And if you are a beginner in signature campaign you can join in facebook, telegram or twitter to earn token. For me the more you have way of earning money the easy way to become rich. Don't focus in just one thing.
