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.
I love to earn in campaign but definitely not my favorite, my favorite way of making money is trading because if I can find a great opportunity to make short term trade I can do it in a little time and I can instantly get profit. I do not want to spend much of my time where I need to follow the rules to get paid, I live with my own rules.
