Signature campaign can give you a not too bad pay however it is not manageable since most and go back and forth. I think the better way is exchanging in the event that you can pick up exchanging build up your own technique and stick to it, you ought to be effective.
Signature campaign is one of my favorite. Besides that, I trade bitcoin. It gives me good income too. The reward from signature campaign is traded in bittrex. Bittrex is my favorite, there are thousands traders so the market is always crowded. If you are lucky you can earn big income in short time but traded needs skill and prediction. You can try with small capital so you will be familiar with the coin price movement. You will be familiar with the low and high price so you can decide when to buy and when to sell.
Signature campaign will accept the members by check the quality of the post and rank only. This will give a decent income but don't know when they close the campaign. You have said you trading would give high income in online if person involved in trading is lucky. It's purely based upon the fluctuation of bitcoin price in the chart. If they price move up everyday. They can see profit, if any drops been occurred surely that would go to loss only.
