Just do some nice signature campaigns and you will be done in no time because its easy and also nice to do if you are asking me.
I think its 100% profit you are making so that makes it even nicer,
That would help but not a lot if you want to grow your money significantly, always put in mind that earning in signature campaign is not a big amount of money because it is just a simple job if you consider it as one so it will only pay you a small amount.
If you are good in savings you can grow your income in signature campaign by participating in short term investment or trading.
